The Oops: While signing autographs outside of the AOL building during her press tour for the new Wonder Woman movie, Connie Nielson accidentally flashed fans when a breeze lifted up her skirt.
The Advice: Aside from staying ever vigilant for the rogue gust of wind, a slip is always a girls best friend.

The Oops: Emma took a chance on a flirty, diaphanous Chloé dress - and the dress turned on her. “My sleeve almost fell off and completely exposed my body!" she told PeopleStyle.
The Advice: When wearing tissue-thin, sure-to-tear pieces, be prepared, as Emma was: "I had nipple covers on in case that happened.”

The Oops: Nicole kindly went to hug one of the tour bus attendees at the Oscars - at the expense of the delicate bejeweled straps of her custom Armani Privé gown.
The Advice: If you're in couture, avoid any sudden movements. And if you do find yourself in a similar situation, hope that your date is as resourceful as Keith Urban was - he fashioned the gown's criss-cross straps into a halter.

The Oops: One of the perils of a custom gown fitted to your measurements exactly is that there is absolutely no margin of error, as Hailee found out at the Oscars when a tiny tear in her Ralph & Russo Couture gown got bigger every time someone stepped on her train.
The Advice: Don't breathe, sneeze or walk too fast - and be sure to pose like a pro, as Hailee did, to cover any evidence until you can get to a safe space to stitch it up.

The Oops: Chrissy knew her incredibly high-slit gown, fastened only with two safety pins on either side, was going to be a risk - and lo and behold, she ended up giving viewers an eyeful with one slightly too-long stride on the AMAs red carpet.
The Advice: If you're Chrissy, you just DGAF - and you use social media to mock those who were scandalized. (Plus, you thank your waxer while you're at it.) She followed a similar strategy in response to her Super Bowl nip slip.

The Oops: Perhaps lured into complacency by the relatively covered-up nature of her paisley silk suit, the star didn't realize things were sliding west until she was halfway to her car.
The Advice: Even Queen Bey can't will a plunging neckline into submission. Relying on a healthy amount of double-stick tape and perfect posture is key to pulling off sexy suiting.
7 of 27
The Oops: She forgot to take the tags off her Céine coat, and wore it "about four times" before the paparazzi caught it.
The Advice: Before you wear anything new out of the house, turn it around and inside out to check that everything you don't want (including inside care tags and stitched-shut coat vents) has been carefully snipped out with nail scissors.

The Oops: While playing a game with Jimmy Fallon, the star paused, shocked: "I might have just fallen apart from behind!”
The Advice: If you haven't got a jacket or wrap on you, you may have to borrow the nearest suit coat (in this case, Jimmy's) until you can make your exit.

The Oops: The Property Brother had an unexpected open house when the seam of his pants ripped - a problem, he confessed, he has a lot with his jeans.
The Advice: If you too find yourself wondering "How does one butt rip so many pants?", bring your favorite pairs to a tailor to get the seams reinforced.

The Oops: Cannes first-timer Caitriona learned the hard way that the film festival's oceanside breeze can be a bit of a bummer (get it?).
The Advice: If you've got to wear a floaty mini for your Cannes photocall, you may also have to keep your hands strategically planted at your hemline. (Alternately, you can just handle it as coolly as the Outlander star did!)

CHLOË GRACE MORETZ
The Oops: The seam on the star's lilac turtleneck top came apart mid-autograph.
The Advice: If something feels too small in the dressing room, believe it. There's no way you'll be able to stand in that perfectly slouched position where it looks like it fits all night. Don't be the girl who splits during a sneeze!

The Oops: A very important seam at the crotch of his pants split right as he sank into a squat, causing a case of extreme exposure.
The Advice: It’s probably too much to ask Lenny Kravitz to wear undies with his second-skin leather pants, so we’ll just recommend that anyone in this particular situation ask a tailor double-stitch reinforcement at key areas.
13 of 27
The Oops: Her navy Miu Miu dress caught a gust of wind outside the line’s Paris show – and caught the star in turn by surprise.
The Advice: Doing exactly what she did – wearing a pair of full-coverage undies under a lightweight skirt – means your Marilyn Monroe moment is more saucy than skanky.
14 of 27
The Oops: The supermodel experienced a wardrobe malfunction “of the highest caliber” when her Solace London dress split all the way up the front.
The Advice: If your clutch is too small for a sewing kit, make sure it’s big enough to serve as a modesty shield in the event your high-slit dress turns on you.
15 of 27
The Oops: The Victoria’s Secret model endured “20 minutes of lunges and squats” with a split seam before someone told her.
The Advice: You’ll never be sorry you kept that extra hoodie in your gym bag for moments just like these.

The Oops: Navigating the tricky stairs in Cannes, the French actress pulled her skirt apart to aid her movement, inadvertently giving the crowd an eyeful.
The Advice: Fashion tape works below the belt too. Securing a super-high seam (or a mishap-prone wrap silhouette) may be the smart solution if you’ll be doing more than sitting all day.

The Oops: She revealed way more than intended while leaning over to untangle the hem of her gown post-Golden Globes (and we’re not talking about her upper thigh area, which she bared on purpose).
The Advice: No matter how small your chest, if you’ve picked a dress with a cutout to your navel, you’re going to want to invest in some fashion tape.

The Oops: The mom-to-be gave the paparazzi an eyeful of her most famous asset in too-sheer skirt.
The Advice: Hold your clothes up to a window in bright, natural light. Can you see through them? Then undergarments are advisable.
21 of 27
The Oops: She had messy brown smudges on her white leather pants.
The Advice: If you’re J. Lo, make sure to have a backup pair of white leather pants (a Tide pen is just not going to cut it for these babies). If you are not J. Lo, avoid white leather pants altogether.

The Oops: Julianne ripped her Temperley London gown up both legs while dancing too hard at a Golden Globes after-party.
The Advice: Should you be wearing a borrowed gown worth megabucks to a reception with great music, think hard before doing your best “Gangnam Style.”
23 of 27
The Oops: The star busted a zipper on Emmys dress. Click here for her NSFW tweet of the disaster (don’t say we didn’t warn you!).
The Advice: If you’re determined to make that super-snug dress zip, opt for Spanx, avoid sitting down all night and (on the off chance your stylist isn’t waiting in the wings with a sewing kit) bring an opaque wrap so you can make your exit discreetly.
24 of 27
The Oops: Katherine's dress undid itself during her acceptance speech at the ShoWest awards.
The Advice: Spend some time in the garment before an important event to discover any potential issues. If it rides up, dips low or is precariously fastened, you’ll find out before it’s too late.
25 of 27
The Oops: She sported a visible pasty underneath plunging (and sheer) gown.
The Advice: Enlist a friend to take photos of you with a flash camera before leaving the house. What looks great in your bathroom mirror may appear very different in an iPhone pic posted to Facebook.
26 of 27
The Oops: The royal's pretty yellow dress fell victim to a gust of wind.
The Advice: If you don’t have a royal dressmaker to weigh down any hems that might inadvertently give you the full Marilyn Monroe, make sure you opt for full-coverage boy shorts.
27 of 27
The Oops: Emma's dress was ’90s-chic from the front and eye-popping from the side.
The Advice: Find a good tailor who can transform that beautiful but less-than-perfect-fitting piece into a couture-worthy creation.
