This has to be the largest Forever 21 I have ever been to! Normally I find that Forever 21's website has a better selection than the stores, but since this store is ginormous, it has seriously ever single thing that the website does...plus more it feels like! It's neatly arranged with more of the party type clothes (tops, dresses, etc) up front and the more casual items toward the back. As a bonus, there is a men's section toward the back in a corner room.
I definitely recommend trying stuff on at Forever 21...it's definitely helpful because some stuff that looks "long" on the hanger ends up being hoochie mama short once on! I do not recommend going into this store if you are short on time...it takes awhile to go through all the clothes; plus depending on when you go, the line for the dressing room can be long (note: they only allow you to try on 6 items at a time), and checkout can take time. So if you only have 15-20 minutes, keep on walking.
However, the time in the store can be worth it because after spending 45 minutes (at least) in this store, I walked away with a NYE dress for $15!
