One of the better values in low-price shirts is the British shirtmaker T.M. Lewin. The quality of the shirts is decent – generally considered to be similar to Brooks Brothers or other better mass-market American brands – and the styles and pricing are excellent.
Lewin is currently offering five shirts for a hundred pounds – which is about $150. If you’re looking for basic shirts for the office, this is a very solid deal. Unless you’re very big, make sure you buy the slim fit, which is very much a mainstream slim fit (i.e. not super blousy on an average man), not a fashion slim fit (tight on a skinny man).
