American Eagle has some good jeans and shirts for dress codes, but I’ve also noticed a lot of non-dress code things there, so you may have to look a bit!! Hollister also has some good tees and things, and it’s a little bit cheaper than AE. Places like Pacsun have some really nice stuff!! I think Cotton On also has really cute stuff, and most their stuff is more modest which is definitely a plus when you have to worry about a dress code. You could also probably find good stuff at Forever 21, H&M, Wetseal, and other stores like that. Good luck, hope I helped!!
