Hi (first UK post - just discovered you!)
I'm bit like Alenamac and Maamel...
I'm 5'4" and 156lbs - I was a size 16 bum and a size 14 top (unless I was going for the squeeze-myself-into-a-stretchy-top- and-have-to-suck-my-tummy-in, size 12!) and I'm probably not far off being a big 14 bum and a proper 12 top.
I am stuck in that no man's land though - where older, too tight clothes are fun again, but essential every day items are looking v. baggy & rather silly (thinking of my black work pants here... oh dear)
Rebsee - you take a smaller size in knickers than trousers?! Wow - maybe it's just me, but I sometimes I end up with pants a size bigger than my trous, cos I can't stand it when they dig in, even a little bit!
Plus, it should be the law that knickers are sold 8/10, 10/12, 12/14, 14/16, 16/18, 18/20 IMHO!!!! As a 14 bum I wouldn't dream of buying 12/14 so I always end up with 16/18 and having to pull em up all day long!
