Slim fit henleys
Most important of all, only buy henleys that have a good, close fit. They should touch the body pretty much all the way through their length — no hanging or billowing fabric anywhere. If you’ve got a bit of a guy, the henley might not be the best choice for you, especially lighter, thinner ones. It’s meant to be a pretty form-fitting garment. The only place there should be any looseness is up at the collar when it’s unbuttoned.
