A girl who is hot/cute on an almost supernatural level, and so appealingly dressed as well, that she seems to be from a painting or drawing.

Her existence seems improbable yet somehow she is real, and so this burning beacon of raw sexuality falls between being 3D and 2D.
Did you see that girl who walked past just now!? She was practically 2.5D!

Get the 2.5D mug.
