My view is never never never judge your size by the label of clothes. As I have said a couple of times ...the sizing on clothes depends on the country it was made, the cost of the items. The design and cut of the clothing. If you compare clothing that you have bought to clothes that you have, you must remember that wear and tear id a factor fibres change and stretch.
If the scales say you have lost ........ YOU ARE LIGHTER AND THE PLAN IS WORKING!!!!!
I have female freind who will buy something she likes, tries it on, checks her look in the mirror then buys it. Gets it home and cuts the size label out. I thought this was strange, I asked why she did this. I was told that she said my size runs form 14 to 18 depending on what I buy. So is if I dwell of the size I would never feel happy with my clothes. So she said that she buys what she likes and removes the size.
