We're sorry to break it to you, but leggings aren't pants.
Sure, they're ridiculously comfortable and they almost feel like second skin, but it's a huge fashion fail to wear 'em with a tank top—unless it covers your bum. See, when you wear skin-tight leggings with a tiny top, you'll get the most AWKWARD camel toe ever.
You'll also get really odd looks from strangers. Like this.
So how do you wear leggings without looking like a complete fashion victim? Easy-peasy. Layer them with oversized pieces: a boyfriend shirt, a cardigan, a sweater, a structured blazer, or a leather jacket! Anything that can cover your rear end! Finish off the look with boots (if the weather permits), ballet flats, or sandals.
The only time when we think it's okay to wear leggings with something short, is when you're at the gym. Heck, wear exercise leggings with a sports bra if you want to (and if you're brave enough to!).
Like Ellen freakin' Adarna.
