If this if your first ML bra or bikini, we recommend consulting our size chart or reaching out to our team to double-check your size with us!
Bra sizes aren't actually standardised across brands, so it's possible you might wear a slightly different size with us.
FF and GG cups:
We recommend sizing down to an F or a G in our bikinis - except the Emelie Bikini Top, which is quite busty and might feel more secure in a cup size larger than you normally wear.
HH cups, J cups, and size 6 bands:
Simply size up to the nearest Sister Size and fasten the adjustable back tighter. Our bikini tops have been designed to be adjustable down by 1.5-2 band size through the band.
Meet Dolly, our beloved D+ bikini top design, based on the fit of our best-selling Emelie Bikini Top!
As a balconette-style bikini top, Dolly is a very feminine, yet functional piece that is fully underwired to ensure brilliant support, shape and lift! Dolly also has a gorgeous drawstring neckline that allows you to choose your desired level of coverage.
FEATURES
Fully underwired for lift, shape and support
Cutaway design - no excessive coverage here!
Luxe gold accessories
Fully adjustable straps
Adjustable band (adjustable down by up to 2 band sizes)
Powermesh lining
Adjustable drawstring neckline to fine-tune your coverage
Always rinse immediately after swimming in cold fresh water & take care to completely dry any gold accessories to prevent tarnishing
Hand-wash only - to help protect the longevity of your garment, do not machine wash. The use of underwires means that some machines may damage the garment.
Lay flat to dry in the shade and out of direct sunlight.
Don't wear your swimwear on abrasive surfaces and this may cause damage to the fabric.

Customer Reviews
Overall rating: 4.8 / 5 from 58 reviews.
Absolutely love it! I have ALWAYS struggled to buy swimwear as wear a size 10 but have E cup (or at times in life, bigger) boobs.
That just doesn’t exist In most swimwear brands and I end up spilling out everywhere or not having support. The only option was “older lady” brands which wasn’t great either as I’m still In my 30s.
My swimsuit arrived and I am SO thrilled by it - it fits so perfectly! Looks beautiful and is very comfortable and supportive.
I will only be buying your swimwear from now on. Thank you again!
Store owner replied:
ALANDAAAA!! You. Look. AMAZING! We are so happy that our swim has been a game changer for you and that it has made you feel incredible, this is always our goal!!! Thank you for your beautiful review, we can’t wait for you to grow your ML collection with us! 💕
I am absolutely obsessed with this bikini top! I have a very large natural bust that needs support and have always found it so hard to find something comfortable that also is really cute. I think I need one in every colour 😍
Store owner replied:
Oh my gosh Kariiii you look INCREDIBLE! This makes us so happy that you finally found that perfect fit to support you! Thank you for your support and your gorgeous review! 🤩🤎
I have been living in Australia since 2018 and have not found a single swimsuit that could fit properly and support my cup size, and it has been so depressing and difficult because we live on the Sunshine coast and all anyone wants to do is go to the beach all year round.
All the swimwear I have tried would be so weak it would allow under boob because it couldn’t hold weight, threaten to come off because of its inability to support, or simply couldn’t cover my ladies properly.
I felt so secure and supported in this top that I feel I could probably surf in it and it still wouldn’t go anywhere. It also lifted and held the ladies in place which Busty girls know can make the difference in the way their figure looks! I finally can have waist definition again which makes me feel confident when wearing it. I cannot thank you guys enough.
Love the Dolly top. Holds the girls up, very supportive and comfortable to wear. Love the drawstring feature at the front. Perfect for beach or the pool. Wearing a size 14H
The top fits really well and is quite flattering! When I had to make an exchange the people who helped me were really responsive and helpful in finding the right size and answering my questions.
Store owner replied:
Awww Rose we love that you’re obsessed with our Dolly Bikini Top, isn’t she just so cute! So wonderful to hear our customer service team was helpful and efficient for you, thank you for you review! 💕✨
Love this bikini top. So comfortable and supportive. Best bikini top I’ve ever worn.
Store owner replied:
Awwww Mia we love to hear this! It truly makes all the difference when a product is designed specifically for us busty girls! Thank you for your lovely review! 💞
Having a larger bust, it’s always been really hard to find a bikini that fits, but I LOVE this bikini. It fits perfectly, looks so flattering and is very comfy. I also love that it’s adjustable. Super happy with Marvell Lane and highly recommend!
Store owner replied:
We love this review Sophie! Doesn’t it make a world of a difference as a busty lady to find a bikini top that truly does it all?! It’s a dream come true! Thank you for your kind words, we’re so happy you love the Dolly Bikini Top! 💞
Having a larger bust, it’s always been really hard to find a bikini that fits, but I LOVE this bikini. It fits perfectly, looks so flattering and is very comfy. I also love that it’s adjustable. Super happy with Marvell Lane and highly recommend!
Truly the most comfortable and beautiful bikini top I have ever owned! I absolutely love the colour, even more beautiful in person. The fabric is exquisite, buttery soft and you can feel the quality of it. Along with the clever hidden bra that really holds everything in place even in big surf! I love that there's no padding as us busty ladies don't need extra padding. I have previously worn Prima Donna and Freya swim and have always felt that they were a little frumpy with the unnecessary padding and the cuts tended to make me look bigger busted and pushed up, the Dolly top is so well cut and flattering and I don't feel like my boobs are pushed up under my chin! I have absolutely LOVED every single piece I've bought from Marvell Lane, absolutely worth the investment.
Store owner replied:
WOW NATASHA 🥺 this review is absolutely incredible thank you so much for taking the time to leave such positive and detailed feedback it means the absolute world to us! We put so much time and effort into creating the perfect pieces and it makes us to happy to hear those details have been a game changer for you! Thank you 💞💞
I really love the fabric of bikini top, it's very comfortable and a flattering style. I found it to be a sug fit and would have upsized.
Store owner replied:
Awww yayyy Amy! We’re so glad our Dolly Bikini top has been amazing for you and has ticked all those boxes, it makes us so happy to hear! Thank you for your review! ❤️
Store owner replied:
So glad you are loving your Dolly Bikini Top Nicole!! Thank you so much for your gorgeous review 🤎🤎🤎
After years and years of searching ( over 10 years ) , this is the FIRST bikini to actual fit me. I’m a 10/12 G. Such a great fit , and looks amazing . 10/10 recommend .
Store owner replied:
We LOVEEE this review Katlyn!! We are so glad you have finally found a bikini that not only fits but actually looks good. Thank you for your support and for loving your ML pieces 🤎 xoxo
I’m absolutely IN LOVE with the Dolly bikini top! I was a bit skeptical about ordering bikinis online since they rarely fit, but the ‘try before you buy’ option gave me the confidence to give it a go. I’m so glad I did. It’s incredibly comfy, flattering, supportive, and even a little minimising! I never thought I’d find a bikini that truly has it all. Thank you so much Marvell Lane! I wish I had one 10 years ago!
Store owner replied:
Awww Stacey thank you so much for this incredible view! It absolutely warms our hearts to see comments like these, we’re so glad it’s ticking all those boxes for you! Enjoy your favourite new bikini! 🫶🏼🫶🏼🫶🏼 xxxx
I followed the online advice re; sizing. I ordered the basics bra, fitted like a dream love it. Went with the same sizing for the dolly bikin top but felt it was too small in the cup? So will exchange it for a bigger cup. Hopefully it will fit right. I'm not the most confident in my body so I'm hoping a size up will fit better and feel more confident.
This is the best bikini top I have ever owned. I’ve always struggled to find proper fitting bras and bikini tops, even other D+ size brands have been a let down for me. This bikini top fits so well because of the adjustable back and is so supportive. So supportive in fact - I went to the gym after a beach day and forgot my sports bra, as a fuller busted women - I cannot workout, let alone run on a treadmill without a sports bra. I was still wearing this bikini top and figured I’ll just use it as a bra for gym as I had already made the effort to be there. This bikini top was more supportive than other bras I have owned and I was able to easily run on the treadmill for 3kms with no issues at all. I recommend 100% and have been buying so many Marvell Lane pieces since, I am converted. These products are what I have been looking for my whole life. 👌🏽 👌🏽 BUY IT.
Store owner replied:

Thank you so much for your support and for loving our pieces.

Store owner replied:
Thank you for your review Timea! Glad you’re loving the Dolly Bikini Top! X
I waited for weeks for the chance to test this out and give it a proper review! This bikini top is comfy, flattering, and best of all (well at least for me) was great under my wetsuit for a day of diving. Busty lady approved.
Scuba diving lover approved!
Store owner replied:
This is an amazing review, thank you!! We’re so glad it passed the ultimate test under your wetsuit. So happy it’s ticking all the boxes for you! x
Omgherrd!!! This bikini top is exquisite. The fit the look and comfort. No other bikini top I have bought has come close. Thanks again Marvell Lane.
Looks horrible on the body. The fabric inside makes lines on the outer one so it looks like a grandma’s bikini and the fabric under the boob shifts off the frame. Very disappointing.
This piece is lovely but isn’t my favourite - the style is not for me. The fit was fine (I possibly should have downsized) and as a triangle bikini wearer, I was desperate for a bikini top that would take pressure off my neck - which this one certainly does.
Positives:
Adjustability as to the fit and look through the back and even the front tie.
Comfortable for Long (Beach) days.
Doesn’t shift around considerably whether worn on beach or under clothes/moving around.
No sore neck
Negatives
I agree with other comments that the band was a challenge and I had to do it up from front and then turn. Not a big deal for me and I appreciated the range of the adjustability, but inconvenient.
Looked too much like a bra for my taste (and my partner said the same. It felt a little boring. Perhaps a more striking colour like the same bikini in red wouldn’t have been the same but I was looking for black)
The cup has a sort of lump/bump in it that looks odd (again my partner noticed this also).
Depending on what you’re looking for it’s either a total slam dunk or a bit of a disappointment. I really like ML bras but this bikini was a little too plain for me.
Obsessed! The most comfortable bikini I’ve had in a long time. The hook back fitting snug is an absolute dream being an 8GG. I’m already getting compliments because it’s apparent that it’s a quality product that sits very nicely
