I love the Quality of clothes even though it’s cheap. I’ve never bought make up or shoes from them because I’m a little bit scared but I think I might, all I know is the clothes are wonderful. My first swimsuit I bought from them was a little bit big but my second one and third were awesome and I’m waiting to buy and 4th, 5th and more.
