Is the extra fluffiness just an inch or two? If so, then moving the buckle and strap, as Chas described is a good solution. Strap extenders are also a good idea.
If it's a matter of super-fluffiness. the aprons could probably be enlarged.
Actually altering a kilt to make it larger involves a lot work and time. Avoiding that cost could be a great motivator to de-fluff. I hear it's easier for guys than for us ladies.
