Store owner replied: Hey Sharon! So glad to hear you are loving wearing your Dolly One Piece. Thank you so much for taking the time to leave your review 🤎
I love these togs, the first time I haven’t felt saggy or frumpy in swimwear postpartum. Beautiful colour and quality. True to size fit for body, they don’t stretch when wet so I’m glad I didn’t size down. I sized up in the cup to give support without cleavage (16F) and they’re a perfect fit - there’s a bit of space but no obvious gaping and I love being able to adjust the fit with the tie. I have recommended to all my busty friends - especially post boob feeding!
Store owner replied: Awwwww Olivia this is beautiful! Feeling good, looking good and being well supported in one, it’s truly a dream come true isn’t it! We’re so happy to hear you’re loving your new piece! Thank you for your support it is appreciated so much! ❤️❤️ xxx
The perfect swimwear piece!! Supportive in all the right areas!! Flattering cut, and beautiful thick material with the cutest design!!! Will 100% buy again and have already recommended to big boobed sisters!!! X
DOLLY ONE PIECE - PECAN STRIPE
Store owner replied: Hey Lorian! Absolutely love that you are loving your new One Piece and spreading the word to the busty community. We are obsessed with our Pecan Stripe and are so glad you are too xx
The first time I have bought swimwear without crying in a dressing room! The fit is amazing and I feel comfortable and secure. For a busty lady I finally have swimwear built for my shape!
I loved the quality, but I got the sizing wrong, and they were a bit big. Also, the low back doesn't suit my body anymore, which is unfortunate. It's still a great quality product though.
Finally I’ve found a cozzie that actually fits and is flattering! It is super supportive and gives a beautiful shape. I will definitely be buying another!
The best fitting one piece ever !! Have never felt so supported in bathers before
all good
Sizing is perfect!
Great support and coverage. Would be great if it came in a size 18 though as the 16 is a bit snug to put on.
Another wonderful one piece from Marvell Lane! Dolly is so stylish and fun. The colour is great. Also super supportive. Thank you Marvell Lane 💕
Store owner replied: Aww thankyou so much for this lovely review Anna! We appreciate your support and are so glad you love your new swimwear x
Probably the best swimsuit I've ever bought. The fit is great and particularly like the tie-bit on the bust as can gain better 'coverage' pulling it in a bit!
Sooooo omg, my favourite swimwear from ML - the colour is so gorgeous and a perfect fit (after I got an in store fitting at ML) - so good!
I wore my batters for the first time today and I absolutely LOVE them! I’ve always struggled to get anything to fit my bust and this is the first time I’ve actually gotten great support, coverage but still cleavage and been comfortable. Amazing! Thank goodness for your brand - you’ve made my summer with bathers like these 🙌🏼
Just received the Dolly one piece in Coffee today and from the first try-on, I am OBSESSED! After struggling to find a good-fitting swimsuit across my whole body for years, I couldn't be happier that this style fits perfectly in every area and makes me feel super confident.
Store owner replied: We are obsessed with the Dolly one piece too! And we are so thrilled to hear that it makes you feel super confident :)
Hi I was concerned about the it torso part being too long as I'm short but no problem there it fits perfectly, luv it thankyou😊
Absolutely love my swimsuit. I bought the one piece in brown and the bikini top in red so I could wear whichever and not have strap mark changes to contend with. The fit gives me a lovely youthful shape, which as a woman in her fifties is loving.
Dolly delivers. Great fit, flattering around the middle and comfortable.
