One of our band members lost a lot of weight, and I moved the apron edge buckles and the underapron strap a full 6". Yes, the apron was disproportionately large, and the center back was no longer in the center of the back, but, you know what? No one noticed.

So, I guess my advice is, if you've lost weight, just move the buckles, even if it's quite a lot. The hard truth is that most people who lose a lot of weight gain at least some of it back (and the person mentioned above did, in fact, gain back several inches).

If you've bought an expensive kilt that's just too big, and you're going to care a lot how it looks and you're going to wear it a lot, have it taken in. This is not a trivial job and is likely to cost $100-150 if it's done by a person who knows what they're doing. And, if someone tells you they can do it for $40 or $50, they probably don't know what they're getting into.

If it's an inexpensive kilt, just move the buckles.

If you have any more details to give us, we could give you advice that's better tailored to your situation!!
