Short sleeve green patterned shirt - Top Man, $50 Light blue jeans - Levi's, $35 (sale) Brown wing tipped boots - Allen Edmonds, $200 (sale)
A good alternative to a t-shirt on a hot spring day is a short sleeve button up. The key here is to roll up the sleeves about half-up up the bicep. It is much flattering for your arms, especially for men who work out. The fit of a short sleeve is no different than a long sleeve dress shirt (see the Simple Style Manual). The sleeves should never be long enough to cover your elbows. I prefer to wear it untucked and with casual bottoms like jeans.
