A friend is in the States and has found some cheap j brands on hugely cheap sale and has offered to grab me a couple of pairs. I'm a big 12 atm, but shrinking and will prob be a small 12 in a month or so. The sizes are in inches but i'm perplexed. Are the waist measurements for your actual waist, or the waistband of the jeans? Are they generous? Help! I'm in the throes of some major bargain designer jeans hunting!
