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 57 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!
Alanda V.5/5Verified
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 😍
Kari O.5/5Verified
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.
Linda-rose M.5/5Verified
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
Tonisha B.5/5Verified
Love everything about this wish I had gone up a cup size as I find it to be a slightly smaller cup than my bra size, overall amazing piece
Rebecca R.4/5Verified
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.
Rose L.5/5Verified
Love this bikini top. So comfortable and supportive. Best bikini top I’ve ever worn.
Mia5/5
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!

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.
Steph B.5/5

Nicole P.5/5Verified
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 .
Katlyn O.5/5Verified
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!
Stacey M.5/5Verified
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.
Jess D.3/5
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.

Olivia B.5/5Verified
Amazing support and creates such a great shape can’t wait for summer 🙂
Timea S.5/5Verified
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!
Stephanie V.5/5Verified
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.
Ellen D.5/5
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.
Zinya V.1/5Verified
Love, love my Marvel Lane swimmers and bras
Karina S.5/5Verified
Stunning colour, excellent customer service and great quality!
Alicia O.5/5Verified
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.
Mandy N.2/5Verified
Such a beautiful colour, and so much support!
Nat A.5/5Verified

Heidi W.5/5Verified

Lina M.5/5Verified
Perfect fit, very comfortable. Love it!
Christina W.5/5Verified
Fits super well, very supportive and so comfy
Christina S.5/5Verified
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
Savana W.5/5
Fits so well! I really struggle to find bikinis that fit me and this was absolutely perfect :)
Hannagh S.5/5Verified
Fits great, very flattering and comfy, I feel a million bucks in it :)
Fiona W.5/5Verified
So supportive and I’ve never felt confident to wear a bikini top before and now I choose it first.
