The quality of the bathing suit is great! It fits me perfectly and provides adequate coverage. I actually have this bathing suit in another color.
— Roz B.
I LOVE this bathing suit! I always have the most difficult time finding good quality bathing suits that actually fit and this bathing suit has exceeded my expectations!
— Shannon J.
10/10 would recommend. I can honestly say this is the most comfortable suit I have worn in a long time. The fabric is so buttery and soft- it does not cut into your skin but is still supportive.
— Kelsey B.
I just want to say thank you for all of your effort and customer service. I love that you are a small business making it happen!!
