Re: Losing weight and changing clothing sizes
Don't worry about the numbers, just focus on how you feel while wearing the clothes. You'll know what fits best on your body when you put it on. The numbers are just guidelines, and they vary quite a bit between different stores and brands. For instance, a "36" waist at Old Navy is actually 42 or something like that, but at H&M the 36 is actually 36 inches.
For me personally, I gained only about 5lb but my jeans were so tight I couldn't wear them. I went shopping for new ones at the same store and brand, and even going up 3 sizes didn't fit me. I'm pretty sure if I go now to try on jeans again, I'd have to go up even more, to probably a 7 ( I'm 5'3" and weigh 107lb, and I was only a 0 / 1 before ).
