Ok, I am preparing to get myself a kilt jacket and have taken my chest measurement.

However, all websites specify "short, regular, long" but they have no actual measurement as to what constitutes "short, regular, long". Nor has my google fu described it in detail enough that I understand.

I'm 6' tall, with quite short legs, long arms, and a long back/torso. However, about half of the "tall" sized shirts I own are perhaps a tad "too" tall.

Can someone tell me, perhaps an estimate of what measurement constitutes length of the jacket?

Collar to natural waist (in line with navel) is around 21", outside sleeve to wrist is 23"
