Most of the jackets I've seen are cut considerably shorter to allow full display of the kilt. Would be a fashion faux pax to wear a standard length coat? I see from these archive pictures and even our own TheKiltedLaird seem to be wearing them. I ask because I greatly admire the doublet look, (I'd probably find excuses to start wearing the doublet), but won't have the funds to get a full ensemble for some time. Later, it may not be a big deal to get a tweed jacket with scalloped pockets and gauntlet cuffs and I readdress the full kit at that time.
