I actually own a few of them. I’m a little on the fence about it. On the one hand, I would support the brands and buy the real thing — but shoes from brands like Angelic Pretty often don’t fit me. I can only buy Baby’s shoes, and even then some models fit while others are simply too narrow.
As for bags, fit is not much of an excuse — but the material of brand bags has been such that I’m not always impressed by them. So I don’t always buy them real. I have one replica bag that has the actual logo on it, though. I wish I could remove the logo from that and just have it be the generic clock shape.
