Clothing sizes here in the U.S. have definitely gotten "bigger". I remember weight 120 lbs at age 17 and wore a size 9 jeans. I now weigh 155 or so lbs and fit into a tighter 9. To be honest, I have so many sizes (wearable) in my closet right now I don't know what size I truly am!

I have jeans and/or shorts in the following sizes: 6, 8, 9, 10, 11 and 13
Go figure.
