Cute cut, way too small

Loved the color and cut, but the swim suit is way too small. I normally wear a small, but the medium was too small

Not great quality

While removing the tags to hand wash the bathing suit, I noticed that the stitching was coming undone in several areas. I expected the quality to be amazing given the price point. Due to this, I wasn’t able to wear the suit for my vacation. The customer service is also not great. The item is defective and they didn’t apologize for it. They also require you to return it before they provide an exchange. Since the item is defective, they should’ve issued an exchange while I return the item back to them. Again given the price point, I expected the customer service to be better. I mostly likely won’t be ordering again.
