The world stares, then laughs, then makes a mental note to steer clear of tiered dresses and windy nights.
Here Kim is looking lovely in a (every celeb and their cousin-twice-removed has worn it) Gucci dress...
Namely, the pesky zip split. Because even Gucci zips split sometimes (we wouldn't know this, if it weren't for Kim. Thanks Kim).
No? How about boobs, bum or Mitchell brothers hiding down Sofia Vergara's Emmys 2012 Zuhair Murad dress
Okay, we gave that one away...
It's a bum, clearly. Now, let's play, which celebrity lives in a bum like this?
Yup, it's TOWIE's Maria Fowler who desperately tried to conceal the split zip on her pencil skirt.
Moments before tweeting her wardrobe malfunction, to the internet and the world.
A) She's the ex-girlfriend of Rob Kardashian AND an ex-Disney star.
Yes, we know this dress is most definitely not stylish.
But wait until you see what happened next...
Quick, click on the arrow above before you lose the ability to shake this image off. (Also, make a note to never a) wear a dress which looks like you have a napkin tucked in you knickers b) stand anywhere windy and/or turn to the lift and c) WEAR KNICKERS. ALWAYS WEAR KNICKERS.
A time when real talent was recognised and the world looked up to the likes of... well, swimmer Flavia Zoccari.
Okay, this happened in 2008, but Flavia's cossie-cossie swimming cossie split still makes our sides split, a bit.
This happened when French footballer David Trezeguet and his wife B´atrice holidayed in Miami. This also happened to heatworld in Skipton-on-Sea, there the similarities end.
Ain't that right, Cheryl Cole?
A: It's Gwyneth Paltrow.
Even style icon Sienna Miller suffers at the hands of fashion. Kind of.
We can still see the mahusive split in your dress. Also, we still want your dress, please and thank you.
Simply take a David Walliams around with you at all times, should your Balmain dress split down the seams, as above.
The Glee star is all smiles at the Glee 3D premiere in LA... can you spot the closet clanger?
[Her heels are waaaay too big. Obvs] Still, she looks very nice.
Yup, it's the dreaded nipple slip, in case you're too busy wondering who that fella is.
Nippy! Like Nicki! But her nipples out, she we called her nippy! Yeah, it's still not funny, apologies all.
Doing the (style) splits, on stage.
