I second Shane's comments... the "belt loops" on a kilt are actually "sporran loops"... most guys just end up putting their belt through them b/c they fit a kit belt. You can actually wear a kilt belt OVER the loops and it should stay put pretty well.
You are correct about the reason we make them 1.5". This is a generalization, but holds pretty true... customers that only want to spend $110 (as opposed to a $500 wool kilt) on a kilt are generally not going to want to drop $75 on a kilt belt and buckle. They're more likely to want to wear what they already own or want a CHEAP belt ($8 for a 1.5" belt anyone?), so that's how we designed the loops. We built our different models with customer attributes and desires in mind.
If you'd like us to change out the loops and make them bigger to fit a 2.25 belt, send me the kilt and a $5 (for the return shipping) and I'll put bigger loops on it for you!
