The Forever 21 in San Francisco is the biggest one that I’ve been to! Not only is it large and spacious, it’s NEAT which is a rare thing to find in a Forever 21 store. It’s two stories high, and they have very cute clothing. The prices are typical of any girls clothing store, but what’s great about this is that it’s neat. The customer service is non-existent though, so if you need help, good luck finding it.
