i really enjoy OKWISHING! its easy, affordable, and it has very cute clothes! i will say it’s important to really look at what you’re buying. i stay away from items without reviews. also, be sure to measure yourself and compare your measurements to the item’s size chart. do not just say well im normally a medium ill go w that. not a good plan. oyherwise, a great app. ive bought many things including jeans, tops, bathing suits, earrings. i love all of it.
