The Best Shapewear to Wear With Summer’s Trickiest Wedding Guest Dresses

You've got a boatload of summer wedding invites rolling in but zero clue what to wear — let alone the appropriate underpinnings to keep you carefree on the dance floor. The last thing you should have to worry about is an unintentional nip slip or an embarrassing wardrobe malfunction while you're wearing your open-backed maxi. When going braless isn't an option, some serious fashion sorcery is in order. Ahead, you'll find the best shapewear to pair with all those tricky wedding guest dress styles (hello, plunging necklines and daring thigh slits) that you would've otherwise avoided.

Deep V: File under NOT bra-friendly. Reformation is known for their scandalously (albeit sustainable) low necklines, and this floral Callalily Dress ($428) is no exception.

Fashion Forms U-Plunge Self-Adhesive Backless Strapless Bra ($40): Forgo a pair of pasties for a miracle-working U-Plunge bra. Complete with detachable straps and clear self-adhesive wings, the backless style (available in both nude and noir) is designed to lend support and keep the girls in place.

Sneaky Cutouts: To wear a bra or not to wear a bra — that is the million-dollar question. Exhibit A: If the bold print doesn't turn heads, then the cutouts found on this Rebecca Taylor Sleeveless Leopard Bow Dress ($495) fo' sure will.

Hollywood Fashion Secrets Silicone Cover Ups ($12): When in a pinch, Hollywood's no-slip silicone nipple coverups will be your most efficient fashion fix. Designed to conceal and eliminate unsightly bra straps, the reusable stick-ons (up to 25 uses) are known to conquer sneaky cutouts with a vengeance.

One Shoulder: Napa Valley, here we come. Between the sunny, yellow hue and the flouncy little ruffle hem, this Hemant and Nandita Eden Dress ($358) will make you look and feel like a million bucks.

ThirdLove 24/7 Classic Strapless Bra ($72): Eureka! Thanks to a convertible strap (think: five times the fun!), ThirdLove's strapless bra will be your best bet for pulling off all those pesky asymmetrical and one-shoulder necklines — simply fasten the strap and go for maximum versatility.

High Slit: Slay, slay, slay. A black tie wedding is good enough of an occasion as any to reach for this Fame and Partners Kiev Dress ($379) featuring a come-hither thigh-grazing slit and badaboom-worthy neckline.

SPANX Smoothing Thong ($24): The purpose of this seamless nude thong is two-fold. Besides eliminating the ever-dreaded VPL (visible panty line), it'll also keep your nether regions covered should the wind blow. Phew.
