The re-wearable bridesmaid dress is the holy grail of wedding wear, and we've made it easier to find than ever. First, though, adjust your thinking: These aren't your mother's bridesmaid ensembles. Rather than picking a staid and ever-so-boring strapless frock from your wedding palette, do your gal pals a favor and sign them up for matching cocktail dresses from the spring 2010 runways. Here, our top looks.

Betsey Johnson: Look 6

What better way to let your sassy bridesmaids shine than in a flirty frock by the queen of spunky irreverence herself? Straight from Betsey Johnson's spring runway show, this twisted tulle confection lends itself to both a chic wedding and a wild after-party. ($428; betseyjohnson.com)

Costello Tagliapietra: Look 20

This classic, feminine piece from Costello Tagliapietra epitomizes refined chic and is endlessly versatile. Try it with a silver or bejeweled belt (a great bridesmaid gift) on the big day or with a structured patent belt and blazer for work or a night out. ($1,890; by special order at costellotagliapietra.com)

Cynthia Steffe: Look 44

Grecian goddess meets new-school Victorian in this expertly draped jacquard number by Cynthia Steffe. The simple, strapless neckline and tulip skirt are universally flattering, and the draping detail adds a hint of intrigue to an otherwise traditional silhouette. Added bonus: The pearly gray pattern lets your bridesmaids jump on the print trend after the wedding. (Price upon request; neimanmarcus.com)

Doo.Ri: Look 12

Cool-girl favorite Doo.Ri Chung didn't garner all that critical praise for nothing. An expert at graceful jersey draping, it's no wonder pretty young things adore her. She sent a stunning army of patterned dresses down the spring 2010 runways, all of which straddle the line between tailored and twisted. This cobalt blue mini flatters every skin tone, and the addition of a waist-cinching belt will ensure each one of your bridesmaids looks her best on the big day. ($2,495; The Room, Hudson Bay Company)

H&M Garden Collection

What better way to make your wedding environmentally friendly than to dress your nearest and dearest in eco-savvy frocks? This strapless number from H&M's Garden Collection is definitely the prettiest way to wear old water bottles that we've ever seen—and the cheapest. Pair with some super-high black pumps for a flirty, girly look. ($40; hm.com for stores)

J. Crew: Cotton Cady Serena Dress

Get ready to introduce your bridesmaids to their new favorite party ensemble. Nothing looks amazing on everyone the way a wrap dress does, but J. Crew's Serena Dress isn't content with just figure flattery. Toss in an elongating V-neck, girly ribbon bow belt and just-this-side-of-miniskirt hemline, and you've got a fabulous frock that's simultaneously flirty and ladylike. Best of all, it's available in a dozen shades, so you won't have to sacrifice your wedding color scheme to keep your best friends happy. ($225; jcrew.com)

Rebecca Taylor: Look 42

A sweetheart neckline, royal blue color, fitted bodice and full miniskirt; could a dress be any more universally flattering? Rebecca Taylor's Island Blue Dot Dress is crafted from dainty, polka-dotted chiffon, but the impression it leaves is anything but juvenile. Pair with virtually any color of heel (we love a gold platform sandal) for a bridesmaid dress your girlfriends will turn to time and time again for nights out on the town. ($365; rebeccataylor.com)
