This combination of a harrington jacket and a white crew-neck t-shirt looks awesome and makes you look instantly cooler. Give a more informal twist to an otherwise dressy outfit by slipping into a pair of white athletic shoes. Needless to say, you're looking at a wonderful option for a hot afternoon. Those who are dubious whether you can still pull off edgy off-duty outfits as you step into your 40s, this outfit should answer your question.
