Instant Wardrobe Pick-Me-Ups: 50 Fall Trend Pieces—All Under $50!

The little black dress is a classic staple in every woman's wardrobe-so much so that it earned its own acronym. While the LBD is a timeless piece, designers consistently find new ways to evolve the sexy design. This season we spotted sheer accents, dramatic drapery and off-shoulder styles. LBDs are a seasonless go-to piece destined to get a lot of wear, making it the ultimate guilt-free purchase.

Not many patterns have the ability to evoke the unlikely combination of sophistication and grunge quite like plaid can. Perhaps it's because the print has embodied everything from school-style uniforms to '80s punk fashion. Try the trend with a bold black-and-red miniskirt or a babydoll dress in understated hues. Regardless of how you wear it, the pattern will always be both subtly seductive and slightly demure.

When you want to stand out in exquisite way, step into a richly saturated shade that's icy cool, but not cold. Crisp blazers, true-blue denim, and pleated dresses doused in the compelling color are just clicks away.

Classics are always exciting to revisit-these tailored but sometimes casual pieces have a streak of eroticism that make them exciting to wear. Lamé tops, tweed separates and extra-wide pinstripes add drama to your day and will seamlessly carry you into the evening. Slip one on and see where the night takes you.

Animal print isn't a novel concept, but when fresh styles slinked down the runway this season, it was apparent that all things animal should be closet mainstays. For a new, fierce spin, experiment with non-traditional shades and mixed prints.

As the happy medium between too-tight skinnies and excessively slouchy slacks, tapered trousers are the way to go. Take on tailored styles that sit at the waist and flow down to reveal a sliver of ankle. For comfier, more playful options, try printed loungers that narrow at the ends. Pair them with a sharp blazer and stilettos to dress them up.

As the saying goes, "Less is more," which designers revisited this season. Stripped of superfluous details, these structural pieces relied on clean lines and elegant silhouettes. Slip on a nude pencil skirt or a lapel-less blazer for an air of effortless sophistication.

A handful of designers included moto jackets in their looks for fall, pushing these intimidatingly cool pieces to the top of everyone's wish list. But with some marked in the hundreds (of dollars), we found alternatives within reach-and still on-trend, from contrasting sleeves to rich hues.
