Just Frumpy

We have here someone in sweatpants with a sweatshirt round her waist. What's so wrong about that?
1. Sweatpants make people look dumpy. Why? Because they do not conform to the natural curves of the body, they're made of frumpy material and they're always either baggy (which makes a person look bigger) or too tight (which is just plain bad. Period.). When you go out in public, think of what would happen if someone photographed you and put you in a magazine. Would you want to look your best or worst? Chances are you want to look your best. Anytime you are caught wearing sweatpants--tight or floppy--you are probably in "comfort mode" and aren't looking your best. Even if you're going to the grocery store or the post office, you always want to look good. Who knows who you'll see.
2. Yes, it gets hot sometimes and you have to shed heavy layers. Putting layers around your waist, however, creates unattractive lines. The woman here now has a large rump (no matter how large it was before in the sweatpants) and no curves lower than the top of the sweatshirt. Try carrying your sweatshirt on one arm, having someone in your party put it in a backpack, or tie it around your shoulders (gasp!) in traditionally-preppy fashion. You'll look ten times better.
