It turns out even tight clothes can hide fat, on my last mistake I think I was off by a good 10 lbs or so.

I notice all girl's legs look lean in high heeled shoes, including ones on the heavy side. Amazingly even the waist can be tightened up for reasons I haven't fully computed yet in my mind.

What do you guys look at to assess if a girl is heavier than she appears at first glance?
