One of my favorite! The only bad thing is it's not like ASOS which has free worldwide shipping and all their shoes size starts from US6, I'm a US5, so can't buy any.
Sometimes they have bloopers, like once they send me the wrong color, but they refunded me pretty fast and cover my shipping back to them. So I have no issue with that. And the recent order I received, there's a big hole in the jacket and the jacket didn't look the same as on the website. Once again they refunded me pretty fast and ask me to throw away that jacket, don't bother to send them back. I also have a few items that I bought for my sis, it's too big for her as she's too petite. So I just shipped it back, as what I know UO doesn't have free return shipping unless it's their fault like sending wrong item. Hence I have to pay SGD$21 for the shipping to return the items, which I guess another downside.
But overall I love UO. Love their style and pretty good quality for certain brands!
