For your first kilt, if you're not sure how much you'll be wearing it and want something less expensive, sharp looking, cool for hot weather, and durable for festivals and work, I recommend getting a casual kilt in PV from USAKilts.

They're not quite traditional, but they're pretty close. I've looked at cheaper kilts, and in my opinion, paying the extra for a USAKilts casual kilt in PV is absolutely worth it.

If you wear it for a few months and decide you like it, then I'd drop the extra money for a traditional wool kilt.

A lot of people will recommend going straight for a traditional wool kilt. That's fine advice too. But personally, I've spent money on the good stuff only to realize it wasn't my thing too many times. So I prefer a more cautious approach to spending. And if you end up really liking kilts, having one PV and one wool is a good thing.

P.S. Some people swear that wool kilts are good for hot weather if you get a low yardage kilt. I cannot comment on that yet.
