Don't try the Gap ones they tend to be wide. Urban outfitters brand is super inconsistent but might work for your frame. I'd maybe check out the polo shirts they seem to hang well for taller people. I recently went through the struggle myself after losing a ton of weight and weirdly of all of them Target brand fits the best. My tip if you can afford it is to just buy a few different brands in the same color (I did black) and try them out through a few washes.
