With all the planning and energy invested in your wedding day, it's easy to forget about your wedding night—and what you'll spend it in. But your late-night ensemble is definitely worth planning for. To help you, we tapped Rebecca Apsan, owner of Manhattan lingerie boutique La Petite Coquette and co-author of The Lingerie Handbook. With her help, you can find a gorgeous look that fits your body type—and style. Here are her fit tips, along with our favorite flattering picks.

Tall or Long-Torsoed Brides

Emulate another long, lean beauty icon in Eres Paris' fine lingerie line, modeled by the always-gorgeous (and epically tall) Lara Stone. We love the Helois bra and Apollon panty in Beurre Frais, a sheer little number that consists of a bralette, boyshort and an endless supply of sex appeal. ($160 to $290; eresparis.com)

Athletic, Boyish-Figured Brides

"I recommend something to show off their legs and a good bottom—possibly a boyshort," says Apsan. Our pick: Chantelle's iconic Africa fashion line. We adore the demi bra, and the shorty absolutely proves that covering up is sometimes just as sexy as baring all. ($58 to $98; brasmyth.com)

Petite or Short-Torsoed Brides

Vertically challenged brides know lengthening their bodies is a priority, and maintaining a solid line from shoulder to hip is the easiest way to do it. Keep that solid color on the sexy side with Simon Perele's bridal line, complete with corsets, thongs, garter belts and stockings designed specifically for a woman on her wedding day. The smooth expanse of white silk on this number will make you look long and lean. ($57 to $175; simonperele.com)

Curvy, Full-Figured Brides

"Many women feel that if they're full-figured, they can't wear a sexy bra," says Apsan. "Not true." Elomi's lingerie line echoes that sentiment: They carry even their skimpiest and sultriest styles all the way up to a K cup, and produce corsets and garter belts in plus sizes. We love their basque corset and thong set for a sexy, classic look. ($18 to $90; elomilingerie.com)

Small-Chested Brides

"Women with small chests are always looking for something that makes them look sexy, but not padded and fake," says Apsan. Enter The Little Bra Company. Determined to give small-chested women the extra oomph they desire without ever looking overdone, the line features tasteful pushups in gorgeous designs. We love the Lucia bra and thong from their recently launched bridal collection. ($26 to $58; thelittlebracompany.com)

For Large-Chested Brides

It used to be that the well-endowed women among us were relegated to plain, staid undergarments without so much as a hint of lace. Elle MacPherson has since become the patron saint of busty girls, as her namesake Intimates collection features sexy, feminine lingerie all the way up to a G cup. Our current bridal obsession: her Cloud Swing bra and thong in white with a pop of turquoise on the waistband—what a way to wear "something blue." ($32 to $68; saksfifthavenue.com)

Tummy-Conscious or Butt-Conscious Brides

The slightly shy lingerie customer "needs something a little flowy," says Apsan. To slyly conceal trouble spots, a babydoll is just the ticket to provide coverage without sacrificing sex appeal. We're all over Jonquil's Tuxedo babydoll for a sassy take on the menswear trend; though it playfully borrows from the boys, there's no doubt the feminine lace detail and delicate spaghetti straps will wow him on the wedding night.
