imo AE is more of a teen/high school store.. not a men's store.. Even though I'm no longer in their target market, I still like their fits the best for button ups.

Depends on OP's body type I guess.
If you have a skinnier build I suggest AE/Hollister.. Even their regular stuff is already "slim fit." So their "slim fit" stuff will be even more form fitting.

If you have a medium/average build or above, then try Gap, Old Navy, H&M. These stores never fit me properly. I find the arm pit area and below are always too baggy/loose.
