With designers showing off their new fall lines and September issues bursting with images and articles of the new season, everyone is swapping their summer wardrobe and warming up with something a little less revealing. So how can you stay on top of your fashion game? Try one of (or all of!) Fall's Top 4 (yes, 4) trends. First, polish off a look with a newly popular accesory: geek glasses (picture clear, classic Ray-Bans). These glasses have been seen at shows that include Jason Wu and Prada. I recently paired them with dark wash jean shorts, an oversized "The Smiths" tee to look like a tank top, a straw and plaid fedora, gladiators, teal bangles, a teal geode slice necklace, and a borrowed-from-the-boys brown woven leather belt. Second, trade in your skinnies (so last season) for a pair of leg-lengthening, high-waisted flare jeans. These pants do wonders in terms of "growing" you longer legs and pair perfectly with just a simple graphic tank. Third, toss out your neons and trade them in for a calmer approach: neutrals. Tan (Burberry trench tan that is), brown, and black are all big on the runways. At Michael Kors, they were both mixed all together, as well as shown seperatley in an all-tan or all-black ensemble. If you don't want to go all out in neutral, try a hued top with jeans for bottoms, embracing the trend and putting a personal spin to it. Fourth and finally, keep it simple this season by going with a few pieces with clean lines such as a fitted blazer or pencil skirt. Avoid piling on a ton of necklaces and go for a small one or none at all instead.
