You'd do good with either a SW or one of our Casuals (depending on the material you like better).

As far as our casual goes... When a guy comes in to get measured and he has a good bit of "girth" to him, we suggest that he wears the Casual up around the naval rather than on the hips. If you have "girth" and wear it UNDER your belly, it accentuates the gut. If you wear it at the widest part of your gut (typically around the naval), it actually helps to keep it up and it helps to hold the stomach in a bit.

If you have any questions about how our kilt will fit, let me know!

I'm sure you'll be happy with whichever kilt you choose.
