Aeropostale (T-shirt + Aeropostale logo = $30):
This brand is usually more popular with tweens and younger teens; it's pretty rare to see people over 13 wearing Aeropostale... unless you're like a late fashion person like me. I like to call Aeropostale, the "easy brand". It's hard to go wrong with this one! There's no frills, no ruffles, just your average t-shirts. But, that can also be bad. I mean, all they do is take a t-shirt, add Aeropostale on it, and then make you pay $30 dollars for it.
This brand would be the second-easiest brand to be able to match outfits. They don't have a ton of variety, but they have a lot more than Aeropostale. The whole theme of Hollister is California, more specifically Californian beaches, so if you're looking for something light and breezy, this is your store! I really like this brand since you get to experiment with things other than t-shirts and they have a lot of pretty skirts, but there's only one problem: everything's so short! Really, if you bent over while wearing one of those dresses, you would show off your tightie-whities to the whole world!
Alright, out of all three of these, American Eagle has got to be my favorite. They have the largest variety, and their dresses are actually a reasonable length. Their clothes have sort of a vintage-y feel to them (correct me if I'm wrong) and I love all of it! The only part of American Eagle I don't really like that much are their shoes, but then again, they're most popular for being a clothes store.
