It can be a good or bad thing.
It could mean they think you're very good looking, almost perfect.
But it could also mean they think you think you look like that, and that you're naïve, shallow, and not very smart.
I know from experience what you're talking about though. My guess is you're blonde, have pink lips, flawless skin, and probably blue eyes, and a good figure. You should send me a pic or email me and tell if I'm right firstname.lastname@example.org
