Is it me or have sizes changed? I took out a pair of old jeans size 6 this weekend. I mean real old..like 20 years old....and they got on, but do not ask me to breath in them. Today, someone here at work hd a pair of size 6 jeans she asked me to try on becase she said I looked the same size as her neice...they fit perfectly (old Navy)..So whats up?
