Wet Seal is a pretty cool store when it comes to selling cheap and trendy clothing. They carry nice clothes (like those with sequins or whatever) and pretty awesome accessories.
However, lately their quality in clothing has been decreasing...never buy their sweaters or whatever because they're made of man-made polyester that feels like plastic and form fur balls after the first time you wash them!
They do sell some nice things, htough, if you look harder. I recently bought a pair of brown corduroys with sequin back pockets that strongly resemble those of Abercrombie's. They're nice and they were only 14.99, so if you look harder in the store you will usually find something nice.
Workers in the store don't really help you out but that's okay, they let you search for what you want instead of towering behind you all the time.
