I write with very, very heavy description, but I spend next to no time describing characters, even if it's someone my pov character encounters. If I do describe characters, I prefer to focus a) on vibes, and b) to work elements of character throughout interactions, i.e. the classic of "Light slid across his dark hair like silk."
POV characters, however, they aren't getting anything but their own perception of themselves, and I like the idea of readers drawing images from the way the character acts/thinks. Although I did have to add a couple of pointers on my MC in Stains because someone thought my 22-yr old scrawny, dark-haired MC was a balding, chunky middle aged man 
I think it's because, despite writing a lot of description, I don't laundry list it. All of my description is active and "moving" and entwined with thoughts, so I don't have the place to sit and describe a character outside of my POV character's reaction to them.
e.g. Casper's first time seeing Cain, the love interest - nothing on features, but i think it gives a good sense of him
Then Casper saw him, and he couldn’t quite believe he’d managed to miss him the whole night.
Casper didn’t know what it was about expensive clothes that made them look expensive, but no matter that all he wore was black slacks and a loose white shirt, the scent of money just rolled off them. Perhaps it was the way the watch on his wrist hung real-gold heavy and posed like a work of art all at once. Perhaps it was just the way he wore them – even leant against the end of the bar nursing some of that watered-down whiskey, his posture was a billion dollars. Straight back, easy hips, loose shoulders.
The alcohol warmth lifted into Casper’s chest and spilt over into his groin.
Absolutely fucking gorgeous.
A crooked smile touched the stranger’s lips, one that failed entirely to hide that something breathless in his features as Casper met his gaze.
