You ordered something online, but it looks completely different when it arrives. For one thing, you didn't notice the weird shape of the collar or that it said "Mondays Suck" in small print on the back.
A tip from a Reddit post for avoiding this problem: look at the clothing item in the lightest colour before looking at it in other colours. Lighter colours let you pick up on details you would have otherwise missed, and you can see them more closely without them blending into the shadows.
For example, take a look at the side-by-side comparison above of a blouse from shopping site Zara. On the black blouse, the details blend into the rest of the blouse, but things like the ruffles above the shirt cuffs and the shirt tie appear more clearly in the nude pink version.
You can also notice things that you normally wouldn't have in lighter versions, such as how see-through the clothes are.

On the other hand, black clothing is helpful for noticing stains on mirrors.
