@profk compliments on things people have chosen like clothes is a way safer bet of it coming across well rather than creepy when you don’t know someone well than if you pick physical features to compliment.
From my viewpoint- compliments to women you don’t really know:
Those are really nice shoes/that’s a really good dress/I like your bag
= “I am paying attention, and I think you have good taste and look nice”
That dress really shows off your figure etc
= “I am kind of a creep- I only think about your body and don’t care about being inappropriate or making you uncomfortable”
