Tape Your Belt in Place
See the trouble, is if I try to wear a belt high up on my waist, there's this long tail flopping around. I've tried different things, tucking the belt around, making a paper-clip keeper (--really). The textbook answer is to buy a different belt. But I could hardly bring myself to spend the money on the first one!
Enter double-stick tape. The kind you use to hold carpet down. That is what's holding the tail of my belt in place in the high-waisted picture. Removing the tape right after changing, I didn't even damage my $4 belt. That works for me.
