Shorts... in winter?

My Sims are weird.  They like to wear shorts in the middle of winter.  Oh, well.  I just insist that they wear tights underneath; then they won't complain that they're cold!

These are the teen shorts from Family Fun Stuff (I think... someone correct me if I'm wrong!) but I put them with a pair of Yuxi's boots and some tights.  The original teen shorts were low-waisted, but I think I'm going to change that because my little girls never wear midriff-bearing tops (and even if they did, the shorts don't need to sit that low).  Back to MilkShape...
