I think Charlotte Russe is extremely similar to Forever 21, except for at times it can be more expensive than Forever 21. However, it has the same vibe and same type of clothing, except sometime made with better quality material.
They have cute tops for girls to go out in, a ton of accessories like earrings, necklaces, belts, etc. and tons of jeans and dresses. I got my graduation dress here and got a great deal on it.
The staff at this particular charlotte russe is very helpful when you're paying but not when you need a dressing room or anything else.
