Next Level Spring Pastels

While an all-neon number is made for nights out, you鈥檒l get the most wear out of dresses that mix bright hues with neutrals, but any pattern 鈥 from geometric color blocks to pleated stripes 鈥攊s fair game.

1. ASOS Plain Colour Block Mesh Panel Maxi Dress ($135): We dare you to not twirl in this maxi. Ribbons of color make this number a total head turner.

2. Target 3Hearts Colorblock Shift Dress ($25): We love that there鈥檚 not too much color going on on this breezy shift 鈥 all the better to showcase a pair of statement pumps.

3. Cally Coolor-Blocked Tunic Dress ($248): The neon cuffs make this long-sleeved tunic dress feel fun and flirty even with the extra coverage. Work-to-date-worthy? We think so!

Bandeau Bra Cutouts

Spring鈥檚 sexiest silhouette is also surprisingly one of its most wearable (bye bye fashion tape!). Taylor Swift鈥檚 take on the bandeau dress shows just how elegant side and shoulder cutouts can be, while Zendaya鈥檚 colorful version takes it in a more playful direction. DIY the latter for spring break with a thick bandeau ($4) or strapless bathing suit top and a muscle tee-cut top. (Photos via Frazer Harrison/Getty)

4. Nasty Gal Side Step Crop Top ($48): Paired with a high waisted skirt, the cut of this crop top flaunts your shoulders more than your stomach.

5RadioBandeau

5. Missguided Fay Cutout V Neck Bodycon Dress ($50): Prep meets party in this jumper-dress hybrid that turns plunging necklines (and sides!) into unfussy details.

6RadioBandeau

6. Topshop Sheer Striped Skater Dress ($70): Sheer panels help give the illusion of the bandeau style in a more familiar fit-and-flare silhouette. Add to the sweet look with a peachy lip and a thin cat eye.

Tuxedo-Style Details

Menswear-inspired styles are still having a major fashion moment as Gina Rodriguez and Iggy Azalea show off with their tuxedo-style looks that are still so totally femme-feeling. To hit that mark, look for pieces that borrow details like a crisp collar and luxe looking fabrics. Since it鈥檚 all about flawless tailoring, take a little more time making sure they fit.
