out of your league
out of your league — an expression to say someone who is too good for you [urban]
In Friends, Ross was in a game to list five hottest celebrities he dreamed to sleep with. On his list, one was Jessica Rabbit. Rachel teased him, “You do realize that she is a cartoon, and way out of your league?”

Someone is “out of your league” when they are too good for you (which is relative, but nonetheless)
It usually means that they are “hotter than you” so it usualy points to physical appearance.
But it can also be finanially or educationally. Although it mostly used for LOOKS.
