1909 Military tunic...

[Tarheel]

Finally, something I know about. The proper length of a sleeve by US (and I assume UK) military regs. is to the top knuckle of the thumb so as not to hinder the uniform unsightly when saluting. The earliest B & W photo of the proper tunic sleeve length is seen on the troops. The officer in the white jacket has his uniform too short in length, being at the wrist. I would have gone with the long instead of the regular length for the extra cloth in the sleeve. I too am 6' and found that length is a problem in mass produced uniforms. The hem of sleeve can only be reduced with a hem and not stretched if too short. Photo of Downunder Kilt's jacket is the proper military sleeve length. I hope this helps.
