People often ask me – usually at parties – if I walk around every day critiquing peoples’ outfits. While I can turn my critical eye on and off, and I certainly never go up to anyone and give them my opinion unsolicited, there are certain mistakes that I see consistently. If you’re someone who cares about how he looks (and I assume if you’re reading this article, you are), read on for three common errors and how to easily nip them in the bud.1) Loafers with your suit – I get it. Traveling in lace-ups is no fun. Try a monkstrap instead, like the pair above. You can slip in and out of them, and they work with a suit.2) Wearing pants that are too big in the waist – If your belt loops are pulling up when you tighten your belt like in the picture above, it means the waist on your pants is too big, and you run the risk of having diaper butt. Go down a size and your pants and belt won’t work against each other.3) Mismatching themes – I often see guys in preppy polo shirts or khakis wearing things that are edgy in feel (like a biker jacket or boots) elsewhere in their outfit. It doesn’t work. If one piece in your outfit is preppy or conservative, the whole look should be such. Likewise, if one piece in your outfit has an edge to it, the rest of your outfit should too. For example, you wouldn’t wear a rough and tumble boot like the one above with a pair of traditional khakis. A pair of dark jeans or slim dark dress pants would suit them much better.Have you ever made any of these mistakes? Fess up! I’d love to hear where things have gone awry for you. Leave me a comment below, and perhaps I can offer some additional solutions.
