I have the same problem. I used to weigh a good 125 pounds more and while I still have more to lose, I also still dress like I’m the same size. It’s my comfort level. I still think I’m the same larger size in my mind. I’m at the point now, when a smaller loss makes a quicker difference clothes size wise, but my first instinct is grabbing something 2 sizes too big to try on first. She’s been dressing that way since the show started, so a good 10 years now, it’s going to be hard to completely change her style now.
