Customers praised this cinnamon one-piece for its flattering fit that "snatches in all the right places" and supportive design. The "buttery" soft fabric, beautiful color, and halter neck with open back detailing received high marks. Many shoppers loved it enough to purchase in multiple colors. One customer advised sizing down for optimal fit.
- The fabric is buttery & divine, the colour is stunning
- Snatches my body in all the right places & I get so many compliments on it
- Comfy and surprisingly supportive for a 12F
Felt spicy in this cinnamon one piece 🌶️ 🔥 Love it! Thank you MN
Cannot fault this piece! Hands down my favourite one-piece from MN to date. The fabric is buttery & divine, the colour is stunning, and OH MY GOD - can we talk about the cut?! The halter neck and open back is gorgeous, and the under bust detailing shapes the whole piece beautifully. 12/10 on this one!
Fitted, sitting right in all the places you want it to be. I love the colour too, such a beautiful soft tone
Comfy and surprisingly supportive for a 12F went with a size large
This is so comfortable. Fabric feels so soft and no dramas with working out in.
Love, love, love
Another perfectly fitted one piece with the most buttery and comfortable material. I love how the back on this one is a little higher than other one pieces. And the way thw waist is designed makes you look snatched. Would love this in other colours!
Soft and comfy fabric, delivery is super fast.
Love love love!!! Sooo soft! Needs more bust support but I had the strap altered.
Absolutely LOVE this one piece. Snatches my body in all the right places & I get so many compliments on it. Stretchy material but also a nice firm fit. Will definitely be purchasing it in black too!
Love this piece so much! It's really comfortable and the fabric is so soft. The style is very flattering and perfect for when I go for runs in the warmer months. I just wish it had pockets.
Absolutely in love with this one piece. It makes me feel so strong feminine and powerful when I am wearing. Especially love this for back days. So glad I got past my insecurities as a curvier woman and bought this amazing piece.
Soft, comfy, convenient . Sizing was a little small in the top but large in the bottom.
Great material
My most favourite one piece and so flattering, was great to wear even during pregnancy, Love the halter neck style
Love it, good quality. True to size. Would love the back to be a bit higher (due to being a broad back girl I feel exposed with too much back showing) but that’s a personal thing. I still wear it and love it. It’s very flattering!
Super comfy really happy with it for sure 1st one I have ever bought and very impressed
Amazing fit!
This is the best one piece, it’s comfy, easy to wear and snatchers you nicely. The open back is amazing, best part!
Obsessed I have in both colours! Buttery soft.
Obsessed I brought in black too!
Fabric was so and comfy. My only advice for the fit is to size down. Looks in credible on!
