I try not to buy anything without stretch anymore.
T shirts from buckle, Mens Express, H&M (Cheap)
Jeans with stretch from Buckle.
Dress shirts with stretch from Express 1MX style
Casual shirt from Buckle athletic fit. Broad shoulder with tapered waist.
buckle is a great store. the jeans i usually buy are the BKE brand, which are great.
they have good prices and sales, with clothes than can actually fit.
