This is a stupid question but I'm baffled about it anyway. I used to be a US size 24 pants and now I am a US size 14 pants. Would I say I lost 10 sizes or only count the evens and say I lost 5 sizes?

I have never really thought about this. But, since the sizing would be down by 2 each time, I'd think it'd be 5 sizes. That is just totally a guess on my part. But, congratulations on the great wt. loss.

I've seen size 19's and 21's before...but not commonly. I've often wondered about this myself.

even numberes sizes are ladies sizes, odd sizes are juniors. Don't ask me why!

Yeah I just ordered a pair of pants marked "15" off of a website called torrid.com

I don't understand US sizing at all...... why don't they just use waist size or something?

Wouldn't that be so much simpler!! Of course, on the other hand, two people could have a 30" waist and one could have 42" hips and the other could have 38" hips, so I'm not sure how that would work. Women need waist and hip combo sizes.

I think you should count 5, but most people would count 10.
It's funny: if they went from a 12 to an 8, many people would say they lost 4 sizes, but if they went up from an 8 to a 12, they would say they gained 2 sizes.
