Oh man, reading this broke my heart!! I'm 5'10" and my weight is in the dead center of what the BMI for my height should be, but I'm still afraid to try on clothes at some of these places because unless you're under weight, or a shorter height and a normal weight, it's impossible not to feel like a cow. Glad to hear that you got down to a weight that you're happy with, but I'm bummed that they made you feel so awful about your body- They were probably just cranky because they hadn't had anything to eat in years.
You are so right!
The idea that someone is not welcome to try on clothing in a store just because of their (perfectly healthy) weight sickens me - everyone, regardless of size, can appreciate beautiful design and be gorgeous.
