Wow, we're almost the exact same size - you're my body twin, but 5 yrs younger

My 18W jeans all got so baggy that I quit wearing them. I can wear a 16 in some brands now, but haven't bought any since it's almost spring and I can switch into some of my closet shopping clothes then. The only smaller jeans I have are pre-vanity sized, so I'm still wearing misses 18 in my old jeans. I haven't had anyone notice that I've lost yet either. I figure that considering it's winter, and I'm bundled up a lot, that nobody will notice for awhile. Even worse, when spring rolls around and I shed the extra clothing layers, everyone will just assume I look smaller because I'm not bundled up anymore.
Some people have noticed that I am carrying myself differently - I'm more confident and not as stressed-out. I just say I'm exercising more and leave it at that. Maybe I'll closet shop today. We're finally supposed to get up to 50 degrees here this weekend, I'll have to see if any of my old spring clothes fit again.
