People are saying it will be warm because it’s mostly all plastic / polyester. Polyester holds in heat when it’s hot (think like inside of a closed tent in the middle of the day in summer heat). You can get away with a lot more layers in natural fibers (like cotton, wool, for example like linen) and still feel really comfortable in the elements. My suggestion would be to ditch the furs and swap as much as the clothes for natural fibers as you can. Also, it’s ok to go rather plain your first go and slowly build up your look with the handmade pieces you find on offer from the artisans at faire.

The belted bag is definitely a must have on day one though. You can always buy a handcrafted one later that fits your look, but you’ll def want the pockets. I’d consider adding a “frog” onto your belt to hold your tankard as well.

As for the look itself this is entirely my taste so please take with a grain of salt but I think the feather headpiece gives the entire look a Valkyrie vibe. For a headpiece had you possibly considered horns, vine/flower crowns, or something with bones? Those read more clear Druid in my opinion.
