Yup yup, better a little too big. A kilt that's too tight in the hips can be pretty uncomfortable in the front too, depending on your shape. My favorite Kryptek camo kilt is no fun to wear right now for that very reason, but about 10 pounds from now it'll be perfect again. When I have a customer working on dropping weight I'll suggest waiting until they're at or very close to their goal before taking measurements, assuming there's not a specific date that they have to have their kilt.
