Reviews

weird butt area but mostly cool

"Shipping was quick , blue colour ist lovely and the design is nice in the front and shoulder area. However the butt coverage is weird. i ordered according to the measurement guide and still the lower back/ butt area - perhaps even more so because of the seam - can’t really decide if it’s a thong or not, resulting in the feeling of it slipping up too high and then needing to pull it down to adjust it again. Maybe committing to a thong or slip lower area design would’ve been more comfortable."

— Barbara (3/5)

Great Suit

"Love the color, material, and that the backside coverage is cheeky but not a thong back. I wish it was tighter around the waist because the tie back mostly just shortens the straps and doesn't really cinch, but fits comfortably and I might buy another color."

— Claire P. (5/5)

I first ordered this swimsuit

"I first ordered this swimsuit in orange in size M, but the colour was a bit too bright for me, so I exchanged it for the black one in size S. I was worried it might be too small because some reviews said it runs small, but it actually fits perfectly. I have a long torso, which usually makes it hard for me to find a one-piece swimsuit since they’re often either too short or too loose. The open back and adjustable straps work really well for that and make the fit very comfortable. The black colour looks so classy and elegant, while the open back and high cut leg make it sexy at the same time. It’s honestly the prettiest swimsuit I’ve ever owned and I absolutely love it!"

— Lisa L. (5/5)

Unfortunately runs very short, fit

"Unfortunately runs very short, fit was ok but I think I’m too tall as my breast we’re barely covered"

— Nina M. (3/5)

Super flattering!

"I love love LOVE this suit! Super flattering to my curvier figure, the adjustable straps are nice, I’m usually between a M and L and opted for the larger size, it felt a bit more comfortable and had better coverage."

— Rosemary M. (5/5)

Not my favorite color, great suit though

"Great quality, I just found the orange color to be a little revealing of what’s underneath. I’m inbetween sizes usually and ended up popping for a size larger."

— Rosemary M. (4/5)

prefer cup liners

"I would prefer cup liners or internal sleeve to add cups ourselves. Non lined cups show nipples, which I do not want to do."

— Marie (3/5)

I love it but someone else loved it too

"I got this suit and it’s perfect! Wore it just a couple times and it has a perfect fit, seems sturdy quality, and nice adjustability. However, someone else loved it too and swiped it off of a drying rack. Was in a safe place where I wasn’t worried about my belongings, probably was a teenager. I’m devastated to have already lost this suit because it was perfect, but someone else hopefully is enjoying it now too."

— Christopher C. (5/5)

Cute simple swinsuit

"Love this black one piece. got a size L and it is a bit snug."

— Brooke T. (4/5)

Rly nice

"Love the open back. I wanted a classy suit that I could wear around my family but still feel good in. I also have a long torso and this fits well, only a very slight wedgie. Fits the bill!"

— Emma J. (4/5)
