When you’re on a road trip, you see tons of rest stops along the way. So many, in fact, that you pass up some of them up because you know you’re going to come across another one a few miles down the road.

Well, the fashion world works the same way sometimes. Styles come and go, but if there’s anything I’ve noticed it’s that a certain trend can probably be traced back two or three times over within the past 50 years. A great example of this is the wayfarer. In my opinion, it’s the hottest sunglass style around today, and you can’t go anywhere without seeing tons of different styles, colors, and shapes of wayfarers. These sunglasses are a perfect example of a trend reincarnated. If you’d seen someone wearing them in ’05,  you probably would have be thinking, “Where did this person come from, 1983?” The wayfarer may have had an up and down road, but its redesign in the early 2000’s has brought it back, and lately you’d probably have trouble walking outside on a sunny day and not seeing a pair.

Something I’ve recently noticed in the J.Crews and Gaps of the world is a hot item that went away in the 90’s and came back in the 2000’s (No, I’m not talking about Michael Jordan). The Denim look is on its way back into your favorite stores–in more ways than one. The most popular that I’ve seen, and surprisingly liked, is the denim and chambray collard shirt. I don’t know where it came from, but it’s as though the late Billy Mays somehow made it into Gap’s design studio and started whispering in people’s ears. Usually I would say that unless you’re Billy, or Paul Mitchell posing for a GQ ad with a rattlesnake around your neck, a denim-looking dress shirt is a no-go. But Gap has brought it back in a way that actually seems acceptable. I will say this though: there are some denim styles that I won’t ever condone. Here are a few do’s and don’ts to abide by when embracing the comeback of America’s favorite fabric.

Do:

1. Find a shirt that isn’t too heavy, or one that isn’t actually denim but has a soft denim look to it, like this chambray one from J.Crew. Chambray is a different material, but to the non-textile savvy eye it looks very much like denim.
2. Be innovative! Jeans aren’t the only way to rock it. Keep an eye out for different items like chambray ties or pocket squares.

Don’t:

1. Over-do it. Although there are some people that can somehow pull it off, none of them are college students. Don’t tuck a denim shirt into jeans. I’m not really big on tucking anything into jeans, but some people make it work. If you’re reading this, however, you’re probably a college student, so stay away from this fashion faux pas.
2. Buy a jean jacket. I’ve read around that jean jackets are making a comeback, but don’t count on that lasting. There are exceptions to this don’t and they all happen to be celebrities. They can do whatever they want even if they look stupid. So just because Kanye has a jean jacket on, that doesn’t mean you can pull it off.
