Clothing sizes have definitely changed in recent years, I know that much. And I've put on a few pounds too, I agree. But the way that I'm told I go down a size when in reality I know I haven't is kind of off-putting. It's nice, but putting on the new size in another store sometimes slaps you in the face with the fact that no, you aren't smaller. Your butt is the same, the number is just different.
I agree that it's terrible to have such a fixation on numbers, but there's always got to be some comparison. An 8 in one store shouldn't equal to a 4 in another. I need consistency people! So, listed below I've got some of my sizes, listed by retailer. I'm about 5'8"-ish, and I suppose you can gather around what my weight should be from the sizes. I forgot to measure myself so none of the hips to waist things. These sizes are about what I currently wear, and while some have stayed the same it's weird to me that things can vary so much.
