Review: Marvell Lane Busty Basics Bra (Size 10GG)
Have you ever been turned away from a bra shop because they don’t stock your size?
Have you spent a small fortune on bras that now sit in your closet because they just don’t work?
Have you tried every brand the internet “swears by” — Panache, Freya, Triumph, and more — only to be disappointed?
And have you worn bras you were professionally fitted for, only to have them hurt your ribs, cut into your arms, leave scars on your sides or along your cleavage, gape at the top, or come with straps so long they might as well be decorative because they can’t be adjusted enough?
If you said yes to any (or all!) of these, I completely understand your hesitation. I’ve been there. But I can confidently say: this bra is not like the others. You genuinely should give it a try.
My first purchase from Marvell Lane was actually a sizing mistake — totally my fault. It was late at night, I was tired, and I couldn’t bring myself to get up and measure yet again for another bra I wasn’t convinced would work. While that order was on its way, I happened to visit a big-bust specialty shop and got properly measured… only to realise I’d chosen the wrong band size in my Marvell Lane order.
When the bra arrived, I had it altered in the band — and that’s when everything changed. For the first time, I had a bra that made my bust look amazing and made me feel genuinely good. No pain. No digging. No constant awareness of wearing a bra. I could actually forget I even had it on.
So when Black Friday rolled around, I didn’t hesitate. I ordered the Busty Basics Bra again, this time in my correct size — and I am still completely in love with it.
If you’re skeptical because you’ve tried everything else, I get it. But this bra truly stands out, and for me, it’s been worth every cent.
As someone who has always worn moulded cups, I was worried that a soft cup might give me an odd shape or show too much nipple outline. But don’t worry — this fabric is nothing like that. It gives a beautiful, natural shape with no show-through, and I couldn’t be happier with how it looks and feels.

Life changing, thank you so much for creating a brand and range that meets the needs of women as you perfectly describe with a smaller frame and larger bust. ❤️❤️❤️
Store owner replied:
OMG Anita! You look amazing in our bra. We are so so happy for you! Thankyou for your review :)
I love the bra and the way it shapes me, I can only wear it for a few hours as the band is a little loose and rubs on my chest and because of that the wires are uncomfortable and the band and wires rub about 2 inches under the bust. It’s the closet I’ve been able to find to a good fit including in shop fittings. Cotton lining would be great add for my skin however I do like the mesh look. In most shop fittings I’ve been told I’m a 14HH but they have all run small. I think I am at 12L but this size is impossible to find so this will have to do.
I had a virtual fitting with Rachel she advised on a 12HH. I haven’t had a bra fit me properly since having kids, I’ve been living in maternity bras! I love the support and shape this bra gives me.
The underwire is taking some time to get used to as it’s been so long since I’ve worn an underwire bra! But overall love the bra and will be purchasing more
I am absolutely in love. It is so comfortable and so slimming. Being postpartum and much larger than im used to (even 18 months later), I thought I would never find a comfortable supportive bra, but I have found it in this!!! Im so in love.
I saw a review that said the stitching if visible under a t-shirt and yes, it is.. but it looks so beautiful, flattering and I love it. Thankfully I purchased 2.
I have a G/H bust and when I say my boobs have never been this high, I mean it! Supreme comfort, buttery soft, breathable and just down right amazing. I really looove this bra!
Love this updated version. I got the 8gg. Its a great fit and so comfortable to wear. Its sold out in this size for this colour but will get more when there's a restock. Love the fact you make adjustments to the bras based on feedback. Love it!
Store owner replied:
Thanks so much for your lovely message Claire! You look beautiful!! So happy you love your bra x
This bra is a great quality and colour. Love the thick straps and supportive band, and adjustable straps. I do find the underwire at the front a bit too hard though (hurts my ribs after a short while) - this is something I found in another ML bra too and it's possible I am more sensitive to the pain due to fibromyalgia, so maybe ML's underwires are just not for me. I am also a little bummed to discover that the seam across the cups is very visible under everything I've worn over it so far, which makes me less keen to wear it. So I guess it is not as comfy or easy to wear as I hoped for an everyday bra, but I am keen to try the new crop for that! As usual, ML has done an amazing job - just a couple features that haven't ticked all the boxes for me personally.
Store owner replied:
Hey Lorin,
We really appreciate your feedback, thanks so much! Everyone's bust shape is different and we're sorry you experienced this with your Busty Basics bra. The Crop should be the perfect option for you! x
As a big bust, small waist girl, finding a good bra that actually fits and doesn’t pinch anywhere or have spillage over the top is so so so hard. Not to mention it being both comfortable and not looking like a granny bra. These bras did just that. I’m so happy! I plan to wear these everyday because they’re so comfy and my back/shoulders don’t hurt as much at the end of my 24 hour shifts. 10/10 recommend to anyone

This has absolutely made our day, Brittany! 🤍 It is so important to feel supported and comfortable during a long day, so we're extremely happy to hear our BB Plunge Bra is doing exactly that for you! Pretty and practical is exactly how we like our bras in the Busty Community 💗 We appreciate your support! xxx
Love the fit! BUT - the diagonal seam on the cup is noticeable when I wear certain fabrics - particularly noticeable under t-shirts and satiny fabrics.
Store owner replied:
Hey Erin, we're so happy to hear that you're loving the fit of our BB Plunge Bra! The diagonal seam provides structure and support and can show under certain fabrics. Thank you for your feedback - we're hoping you're loving the bra nonetheless! 🤍🤍🤍xx
The size guide didn’t work and the bra is still too small. Mushroom top all over the place. no difference with this bra than any other bra I’ve tried, and I’ve tried them all. No one has figured out how to solve small band + large cup life.
I wanted to love this bra, but as soon as I switched the straps once, they never held again. After one wear they just pop off while I'm wearing it. Also the sizing is off despite help from their team.
I went with an online fitting and sent in photos and measurements, the response was fast and the woman that helped me gave me two options for sizing. She recommended my smaller size for the Basic collection and its sister size for the Evie, since it’s more structured. Overall I’m happy with this bra, but it does set my breasts wider set than I’m used too, but after a few wears I am used to the set and it is supportive in all the right places and is very comfortable.
Love the idea behind this bra. It’s always difficult to find a larger cup size bra that you can wear with lower cut tops. However, the seaming in the cup is very visible, even with thicker material shirts. I also had to size up from my typical 32G to a 34H in this bra and maybe could even go up another size.
It’s not the bra it’s self I think I ordered the wrong size. Some material at the bottom of the cups that I don’t get to use. Therefore it’s not the best fit. Threw away the packing & didn’t think it could rerun it
Great material and shape, I do wish I sized up cup sizes which I read to do in reviews after I purchased. Will purchase again but another size. Have swimmers too and the bottoms I think were small for their size as well. But great material and flattering. Love the colour
The seams are really, really horrible across the cups. This was so close to being a great bra but the seams look all puckered and like a grandma bra and under a tshirt look absolutely terrible. I dont know how you can sell something as a “basic” when it us unwearable under a tshirt.
These are the best bra's I've ever worn. An absolute game changer. I basically l live in them. Incredibly comfortable, and I love that they don't have extra bulk.
Store owner replied:
Hey Courtney!! Thank you so much for your gorgeous review of our Busty Basics Plunge. So glad to hear you are loving your ML pieces 🤍 xoxo
I'm not sure who loves this bra more -- me or my husband! I am a 32DDD/10E, so bra shopping is difficult with my small band and large bust. My boobs also hang low, and standard bras don't offer sufficient support and lift. My family and husband have always complained that I need better bras. This is the first bra I have ever purchased that truly LIFTS me! The wide straps are comfortable and hide well under tops. Other bras also seem to make my breasts look wider, where this one gives great support and shape. In the mornings, I like to do my skincare in just my bra and jeans so I can admire how good my chest looks!! Hubby also happy. Thank you, Rachael, for helping me love my boobs! Can't wait to buy more in different colours!
