I have seven: two 5-yard, one 4-yard and four 8-yard. All are 16 oz. but the most recent (which, incidentally, is a USA Kilts Premier), and that’s only because the House of Edgar muted Maxwell was only available in 13 oz. I’ve noticed that the apron of the 13 oz. kilt is more prone to wrinkling than are my 16 oz. kilts. Any slight wrinkling caused by my sporran strap seems to fall out of the 16 oz. kilts in a day or two, but the 13 oz. often requires a bit of steam. YMMV

BTW, I’m in the Houston area, so when I say I’m accustomed to warm weather kilting, I’m not kidding!😀

Cheers,

SM
