MEN
* Colored Shorts - Just like women, colored shorts are an easy way to make simple, neutral tees (or polos) pop! Every man has a white, gray or navy polo, which would look great with a pair of colored shorts. You don't have to pick something wild or super preppy, but try tangerine, red, yellow or light purple.
* Belt NOT Matching Your Shoes - Ideally, a man's belt should be in the same color family as his shoes (brown shoes, brown belt), but the summer is when we can bend that rule.
Most men opt for a brown belt for the summer, but belts can change the vibe and feel of an outfit in an instant. I recommend a woven canvas belt for the summer. Opt for one in a fun color, which will make plain t-shirts, polos and khakis really pop! (Here's an example of a canvas belt from another blog post.)
If you're not sure about the mismatch idea, then opt for a softer and more casual color like gray. There are lots of gray gym shoes and gray belts, which look smashing with shorts, tees, polos and yes, even sport coats!
* Rubber Flip Flops - A flip flop is fine, but rubber ones need to stay at the beach and pool.
The shoe always, always, always, set the tone of an outfit and nothing makes you look more like a college kid (and fashion-newbie) than rubber flip flops. Personally, I don't want to run into my financial advisor, hair stylist or whoever wearing rubber flip flops on the city streets!
If you're looking for a new pair for the beach, then check out Ecoalf, which pays fisherman to pick up garbage in the ocean. Ecoalf then reuses the plastic, rubber and nylon to make very stylish bags, puffy coats, gym shoes, and yes, flip flops! Affordable, stylish and sustainable - now that's a win-win :)
