I think the reason we don't notice on size as much as we have hoped is cause sometimes when we are bigger we squeeze into a smaller size in cause we don't want to admit we r bigger.
i was wearing a size 16/18 when I started sw this time mainly I squashed into my 16's and I know I did cause most of the buttons are loose or they have tears in so really I should of been wearing a 18/20 and when you look at it that way my size 14 clothes that all fit some are loose feels great.
funny thing is now i'm a 14 i wouldn't dream of squeezing into a 12 cause i would have rolls yet when I was bigger I thought I was hiding it.
