for me they just have to be honest about it and since I myself was not always attractive I too can spot a bs'er right off. I do appreciate compliments on my physical genes and or my jeans (which would deff be the truth since I am one of the blessed few older women that can pull off skinny jeans and I am not talking about the ones that look like you're wearing blue jean skin I mean the straight legged cuffed 50's style). Can you tell I love jeans?
Oh but back to the subject I love an honest compliment no matter what it's about.
