I make a lot of my OH's shirts, as he prefers them to shop bought ones. He is quite long-bodied and has a bit of a stoop to his shoulders so any that he buys ride up at the back and look far too short. Mine fit him better! I know he colours he prefers and buy the fabric in those, but sometimes I will buy some that he may not have considered before but that I think will suit him. So far, so good.
Other than that, no I don't offer an opinion unless asked or if there is an obvious stain somewhere very noticeable that he hasn't noticed!!
