Nah, I ain't no smith, and I'm no good at tailoring! I have my stuff made.
Besides, this is LARP, not Reenactment. At most events, there tends to be a bit of a hodgepodge too, stylistically. Which is only natural, since theere isn't one overarching setting that's being played everywhere. There kind of is, in the form of the Südlande campaign - which is a union of orgs from southern Germany who divvied up the fictional continent of the Southlands many years ago, each org playing / managing one country - but that's more to give a couple thousand players a shared world where we're on the same map, but it's still "your country, your call". That means it's a classic fantasy continent, with everything from Celts to Renaissance, whatever each org is into. We're in there too, as the island of Ak'Marant.
Our group is slowly gravitating towards a mid/late 15th century style, but nowhere near consistent enough overall for reenactment purposes, even if we weren't playing a fantasy background. A lot of our
members could do 15th century Reenactment with their kit no problem, including me, but not the group as a whole. And besides, reenactment doesn't really tickle me. I wanna play! And I don't care that my doublet has machine stitching on the interior seams. And if I fancy a jacket that's 30 years later than the rest of my outfit, I wanna be able to go for it, not agonize over the fact it'd be slightly anachronistic to the rest of my outfit.
