Isn't holding trousers up the same as keeping them from falling down? Both answers should be accepted.

Not bad grid - although very easy even with some nice crossovers. I can't help but think you could have thought of something else to go with belt etc.

Fish wasn't accepted but fishes is the given answer. Fishes is a present particip!e of the verb to fish. The plural of fish is fish! Also the belt group hold clothes up not just trousers as suspenders can hold up socks or stockings as well.
