More vanity sizing I went shopping today. I was wearing a pair of Hollister skinny jeans, size 5. I bought a pair of White House Black Market jeans, size 0, and a pair of Lucky Brand jeans size 2.  Here they are from smallest to largest:   Hollister (5)<Lucky Brand (2)< WHBM (0)  I'm a standard size female, BMI 19-20. I'm not underweight. How do people buy clothes anymore?!?  The size zeros were the largest jeans. Go figure.  The shirt I'm wearing is a large from American Eagle and fits perfect (I'm 32DD). I bought some shirts today. They are xs and are a bit too big. I bought some others that were small petite. I'm not "petite."  I'm at a loss as to how a legitimately smaller woman buys clothes.
