Woman's optical illusion dress makes her waist appear unrealistically thin

Remember the dress controversy from 2015? There's a new wrap that's got the internet scratching their heads. A woman posted a video of herself wearing a tight-fitting, marble-patterned dress. When she pulls the waist ties, her midsection seems to nearly disappear. It's an optical illusion. You can see her actual shape before she does the trick. **Language NSFW**
