How did 2013 go for you style-wise? Were you totally on point, or was there room for improvement? I’ve been traveling over the past month visiting out of town clients and doing some serious people-watching while on the road. I was sitting in LaGuardia Airport at 6AM one day, and I started a list of don’ts, which grew at each of my stops (Minneapolis, Chicago, North Dakota, and Palm Springs), evolving into the New Year’s Bad Style Cleanse below. Read on for 14 habits to purge from your style diet.1) Don’t wear a crewneck undershirt with your button-up shirt. Showing your undershirt collar is like showing your underwear, something you don't want to do in public (I hope). This goes for both casual and dress button-ups. I like Tommy John for great undershirts with v-necks that are low enough not to be visible. Here is my review of the brand.

2) Even if you’re traveling, you shouldn’t wear loafers with a suit. Try monk straps instead, as they can slip on and off easily when going through security (tip: packing a travel-size shoe horn will make your life easier).

3) You can leave the top button of your dress shirt undone with a tie, but don’t have the tie hanging down below your collarbone. Your tie knot should be no more than an inch lower than the top of where your shirt collar closes.

4) Never wear a backpack with a suit or sportcoat. It’s terrible for the shoulders. Also, you are going to work, not for a trail run.

5) Don’t wear a striped jacket as though it’s a sportcoat. A striped jacket is only worn as part of a suit, never as a separate.6) Don’t wear a Hawaiian shirt unless you are going to an actual luau.

7) Avoid those hybrid sneakers-shoes at all costs. It’s a sneaker or a shoe. Not both.8) While you’re at it, say no to those hiking-type sneakers for anything other than an actual mountain trek.9) Skip the strong colognes or aftershaves (Old Spice, I’m talking to you) if you know you’re going to be on an airplane. This is a courtesy to those around you!10) Grab the waistband of your pants (yes, right now) and yank on it. If you can pull it away from your body more than half an inch, your pants are too big. Go down in size until you find the right fit.11) Avoid pocket square and tie combos that match too closely (and especially ones that come in sets!).12) A t-shirt is too tight if it pulls such that the fabric creates a diagonal crease from your collarbone to your armpit. Go up a size if this happens to you.13) Don’t be that guy who wears a parka with ski tags dangling from the zips out to a restaurant. Technical/athletic gear is meant for just that – not date night. This includes outerwear and accessories like hats and gloves. One of my favorite brands of outerwear that gets the job done sharply is Aether.

14) Don’t wear ties that are too wide for you. This is true even if you paid a lot for it/wide ties may come back in style someday/your Aunt Edna gave it to you. Either donate or send them to somewhere like Tiecrafters to have it narrowed. Here’s my guide on how to choose the best proportion for you.
