Suspiciously Similar Outfit

Two characters wear any article of clothing that looks exactly like each other, whether it's a t-shirt, pants, hat, uniform, or maybe even a costume. In most cases if both characters discover that the outfit they're wearing is identical, they may become angry about it (especially women) or just shrug it off and go on about their business.

Oftentimes, the real reason that the two characters dress the same is because they were either tricked into it or they didn't realize that the outfit they had was identical to the other.

Subtrope of Dresses the Same. Compare Limited Wardrobe. Not to be confused with Whole Costume Reference.
