Super comfortable and fits really well
I am in love with this!!! This is my dream bikini top style, I love the cross tie in the back, very comfortable.
AMAZING quality!!!
It fit so nicely and was SUPER cute, not only was the swimsuit rather affordable for the price but the response time from customer service was amazing and the swimsuit fit was so comfy but still flattering. love love love love
I'm a size 32DDD and I custom ordered a Sofia top in XL, with extra support added. I'm not sure what extra support was added, but I did not feel supported. I also felt as though the top flattened my breasts and overall did not look flattering. Maybe if I would have chosen a different style it would have looked better, but overall I was disappointed when trying it on.
Hi Hannah! So sorry things didn't work out. We would gladly exchange or offer store credit for your items!
