Caitlin Donnelly models some fall trends, including black tights with shorts and layered tops.

Fashions come and go, and it is always most cost-efficient to purchase timeless items; however — timeless or trendy — sometimes you just have to buy it now! So what’s on the hot list today? Try out these hot new trends — and don’t worry, your wallet can behave later.

Quilted clutch:

Quilted clothing has been popping up everywhere. The quilted-texture adds a unique dynamic to any outfit, so why not find the perfect, quilted purse? But listen up ladies: Put away your oversized, haul-it-all purses and pick out a smaller purse with a hands-free, across-the-body strap. Bonus points for all purses with chain straps!

Black tights:

This fall, wear black stockings with everything. Tights make dresses, skirts and shorts look a little bit dressy, a little bit edgy and a whole lot warmer. Pick up some simple, black-opaque stockings and pair them with your favorite pair of cut-offs or boy-shorts. Stars like Irina Kulikova and Milla Jovovich have been spotted in this look. For your upper half, layer sweaters, sweatshirts and scarves, and experiment with different lengths and materials. For example, if your sweater is long and thin, throw on a thick, warm, cropped jean jacket.

Neon:

Wanna wear some neon? Take the advice of designer Michael Kors to heart: “Always counterbalance. If you’re going to buy something in neon, make the shape simple and classic.” Check out MK’s Fall 2009 collection for the perfect example of a classic, bright tangerine or neon pink dress that will never go out of style. Excuse me, but did you say, “A neon pink dress that will never go out of style?” Yes, trends can be timeless if you choose the right design.

Jewelry:

Serpents are everywhere! Look for slithering snakes on everything from wallpaper and dinnerware to sexy high-heels, clutches and bangles. Need to be charmed first? Check out Jonathan Adler’s Eve Hand, a beautiful art-commentary that returns to the Garden of Eden. Another jewelry tip: be in high-style — wear your rings on the upper part of your fingers.
