Featuring a carved-out neckline and lower-cut side cups, you can wear this crop with almost all of your fashion without it showing. Better yet, it can be worn with all of our Busty Basics Tops. The J-hook means you can also wear it as a racer-back if you'd prefer.

I never thought I could be one of those women in my Pilates classes wearing a cute crop (with no underwire!!). As a size H girl, I have always worn baggy T-shirts but today for the first time I wore this amazing crop and felt incredible. Forty yrs young and fabulous at last!
Store owner replied: Nina we loveeeee this! You look incredible! I can only imagine how good you feel! So glad you’re enjoying your new crop! ❤️❤️
Comfort & style..
Store owner replied: We are so glad you're loving Our Busty Basics Crop 🤎
pretty colour and nice wide band, but didn't separate boobs as much as i'd like
Store owner replied: Thanks for your review Carissa!! Our Busty Basics Crop is definitely our most relaxed fit and is our go-to for our busty community looking for comfortable fit. I have passed your feedback onto our design team 🤍 xoxo
Love this wireless bra! It's very supportive but still with the advantages of being wirefree! I wear it around the house, outside, whilst travelling, when I'm on my period and my breasts are more sensitive... it's just a great all rounder! Love the colour too!
Love! For a no underwire bra AND looks cute I’m in awe. I bought the one in blue earlier this year and knew I had to get a second. It took a hot second to get used to (comparing it to wired bras or the non-wired kind that is more of a yoga bra) but I now really enjoy it and feel comfortable.
Store owner replied: Thanks for your review Rachael! We love the Busty Basics Crop around here, who knew comfort AND support without underwire could be so good! Thanks for your support! 🫶🏼
amazing bra! minimises and lifts
Store owner replied: Hey Reshika! Thank you so much for taking the time to leave your review on our Busty Basics Crop. So glad you are enjoying wearing it!! 🤎
love that this bra is great for the basics and does what it says, only negative is the extra material between the breast area. the extra material would be better placed under the boob rather than in-between
Store owner replied: Hey Sonya! Thank you so much for taking the time to leave your review on our Busty Basics Crop- we really appreciate your feedback 🤎
The most comfortable crop I’ve ever had! With a narrow back and bigger bust I’ve always struggled to find a crop that fit in all the right places but this is a dream to wear. Super comfortable, lovely material and I love all the different colour choices. Will definitely be coming back for more!
Store owner replied: Gilliannn this makes us so happy to hear! Isn’t it just a game changer to have a bra that fits amazingly! Thank you for your lovely review, your support is appreciated so so much ❤️ xx
I love everything about about it!! Firstly it’s so comfortable. The fit is great love the unique mesh fabric and the colour is divine!!
Store owner replied: Thanks so much Ranya! We’re so happy you're loving our wire-free crop and that colour is definitely a favourite here :) !
I was so excited to get this bra but unfortunately did not fit. Will try another size
Had a fantastic in-store fitting with the team when I visited their Byron store, and couldn't be happier with my purchase of the wire-free crop! Its my go-to to wear at home and while running errands for stylish comfort. Love it!
Store owner replied: That's so great to hear Marianne! We're glad you had such a positive experience at our Byron store and that you're loving your wire-free crop. Thanks so much for sharing the love! xx
Unique design for a larger bust. You'll definately want another one!
Store owner replied: Love hearing this Fenella! So glad the fit worked well for you and we appreciate you sharing the love! xx
Super comfy and breathable!
Exchanged for a bigger size and still feel like the cup needs to be bigger. That said, it’s hard to find a more comfortable, more supportive wire free bra, so I’ll likely just keep it and wear it anyway.
Insane how great this wire free option is - totally flattering but very importantly, super comfortable. Love the new colour too!
It’s a weird fit on me, my boobs hang down unsupported In it giving a weird shape and the straps cut in on my back. The fabric and colour are great and I want to love it but the fit doesn’t work for me. I possibly need a band size up and maybe cup down but not sure that would work either. Would love to see extended band sizes in j cups and free or cheap exchanges to get the right fit. I used the measurement charts. There was an issue with delivery but once notified the customer service was exemplary.
In love with this crop! Super comfortable, the extra fabric in the middle really makes a world of difference to keep things separated, and the lift for a crop is incredible (I haven’t even worn it with the J hook yet). I initially had an issue with my first order/size, but was able to exchange it with help from the ever amazing customer service team - and now know it’ll be a favourite.
Love it but should have gone up a size. Gives great comfortable lift.
Really comfortable fit, the band is soft and stretchy which initially made me nervous that it wouldn’t sit securely, however they’ve made it so the band size sits snug around the body without feel restrictive. The sweat catcher is something I never knew I needed but I love! My only concern is that under my arms sits quite high on me, which is smoothing for that area, but also visible if wearing a sleeveless top.
Great fit and coverage
I like it! Fits well, holds everything in. The material isn’t as soft as I’d have liked but overall, still very comfortable and would buy again.
I am OBSESSED with this bra. I fluctuate between sizes 12G-H and went for the H-HH cup and am glad I did because it fits perfectly. It is so comfortable but still very supportive. I love the thick straps, and the little booby towel situation just goes to show that this is a business owned by a woman who knows what it’s like!
Store owner replied: Thanks so much for your awesome review Brit! We’re so happy the crop fits perfectly and meets your needs. And yes, the "booby towel" is a clever touch! It's all about those little details! Thanks for supporting Marvell Lane :)
Great bra for no underwire, holds bust up, good strap support and comfortable
Fits well, lots of lift and super comfy!
No trouble with return to swap for a different size. Easy fix and very happy with my purchases-great support and comfort-extremely well made. Very pleased 😊
It is so comfortable and supportive.
So comfy and breathable- perfect for humid summer days.
