Customers love this ribbed one piece for its lightweight, soft material and gorgeous color. "The fit is so perfect!" Many praise the design and want multiple colors. However, sizing may run small for taller shoppers—one customer noted the Size S was "too short" and tight on a 168cm frame, suggesting sizing up for longer torsos.
- The material is lightweight and soft and the fit is so perfect!
- Super cute look. Gorgeous color.
- Nice ribbed material
Seriously, I need in every colour!! Amazing fabric, soft, feels great, looks great, perfect for gym activities. Im a size 10 and ordered a M and fits perfect. Actually obsessed with it.
Great fabric. Fits to size. I have scoliosis so the back is a little off centre but that's a me problem it still fits well and is very comfy to wear.
She is the moment! What can I even say about this one piece?! The cut, the quality, the fit. . . perfection! Flattering, surprisingly practical (as a girly that loves to lift, a one piece that stays in place is a godsend!), and the perfect piece for showing off those hard earned back gains. Stunning on it's own, cute af with oversized trackies, it's the piece that keeps on giving. I need it in every colour and then some
Super cute look. Gorgeous color.
I LOVE IT SO MUCH
I loved the design of this new One Piece, the fabric is so light, perfect for summer, with a more discreet rib and a lovely colour. I just need to give it four stars because the fit of Size S on a 168cm tall woman at 58kg is too short (especially on the low back) and slightly too tight. What I mean is that you probably need to size up if you have a slightly longer torso but if you also have small chest then I'm not sure if a size M still fits as it should. It also requires that you wear very low underwear or a mini G-string, otherwise the low back might expose your underwear, hence why I can't really trust it to train in it in the gym. I decided to keep it nevertheless, for fun summer nights as a lifestyle piece.
This piece is to die for, looks sexy on but it’s sooo soft and so easy and comfortable to train in, absolutely LOVE it and it’s super flattering on 🖤
The styling of this suit is gorgeous and the back straps make it even more so and it looks absolutely fantastic on my girlfriend.
Love it 💕
Absolutely love this one piece. The material is lightweight and soft and the fit is so perfect! Lots of compliments. I want one in every colour
I LOVED the cut and feel of this onepiece HOWEVER, it is too short in the body and I had to return. I'm 171cm, slim build and it juuuuust barely covered my butt crack. Probs don't buy if you are taller or have a longish torso. Material could be thicker for the price and considering that padding is light coloured - it's a tad sheer.
Complements the body very well. Fabric is soft.
Such a beautiful fit 😍
Love the fabric and fit. Black - So cute.
It was too low on the back. I have a long torso so I felt like I couldn’t wear underwear. Fabric is nice feeling though but I wish the back was slightly higher.
Hi Jodie-Rae,
Thank you for taking the time to leave a review! We're delighted to hear that you love the fabric, but we understand that the fit wasn't ideal for your torso length. Your feedback is incredibly valuable to our design team. If you need assistance with sizing, please don't hesitate to reach out to us.

Looks gorgeous on! Perfect fit!
I bought these in the 3 different colours to wear in Vietnam, omg they have been absolutely amazing, I just put on a wrap around skirt and away I go, they do not ride up which is amazing.
Material and fit is great. Such a soft fabric looks amazing if you have a certain type of body.
Flattering and very comfortable to train in. Looks great on and shapes your body so fine
Unfortunately the fit was big in the torso area, not for the short girls. it puckered at the sides on me. Size was normal MN. Material and style was gorgeous.
Hello Amanda!
Thank you for sharing your feedback. We're sorry to hear about the fit issue, but we appreciate your kind words about the material and style. Rest assured, this feedback has been passed onto our design team for future consideration. We hope to have the opportunity to assist you with a better fitting item in the future.

Love how this looks on, except top was loose but bottom fit perfectly. Great for holiday workouts to beach walks. Material is so buttery.
Love this for material is nice
Nice ribbed material
Fit was good everywhere but the top, unfortunately not perfect size if your bigger up top however overall options and navigation via the website was perfect. Have been buy from muscle nation for 2 years and will continue to do so
Absolutely love it
I took a risk with this one. It fits well and it's different. Would I work out in it in the gym? Most likely not enough support for me but for a walk yes.
ITS STUNNING I LOVE
Incredible comfortable! I was worried about the white being see through however it isn't at all.
The white is so fresh!
Very nice! Hugs me in all the right places 👌
PERFECT 🤩
