Alright, here's my list. And I shop "normal" brands too, I just try to choose the lesser evil when I have the choice. And I don't do extensive research on brands, so no guarantees. Some of these aren't marketed as sustainable, but are made in Germany or Europe which I think is a good thing (no child labor, no toxic chemicals being used and so on).
Clothing (in random order)
HessNatur, Lanius Köln, Armed Angels, Bleed Clothing, Seasalt Cornwall (jackets, coats and summer dresses), Thought Clothing, Komodo Clothing, Nomads Clothing (summer dresses), Alma & Lovis, Good Society (jeans), Armor Lux (breton shirts), Schneiders Salzburg (wool coats), Brora/Johnstons of Elgin (love their wool or cashmere scarves/gloves/hats/sweaters/cardigans), Falke (socks and hosiery, made in Germany), Toast (mostly secondhand wool sweaters), Living Crafts, Grüne Erde, Engel (underwear), Veith (best hiking socks), People Tree, Icebreaker
Shoes (I have wide feet):
Waldviertler, Think Shoes (I think most of my shoes are Think now), Birkenstock, Trippen (beware, these are in-your-face),
Meindl (hiking boots made in Germany), Legero (lightweight sneakers)
Accessories:
A lot of my jewelry was actually handed down to me. I like Majorica for (fake) pearls. I bought a cheap Casio F91W for my travel to New Zealand and Australia and have been wearing it since. I've been using the same scarf every winter since 2014 (Johnstons of Elgin cashmere stole) and still love it.
Most of the bags I bought over the last few years are from Tom Bihn, I love their bags for their design and practicality. Plus the colors are lovely too. I
still have a "nice" handbag for dressing up though. I really like Volker Lang for leather goods, I'm going to buy one of his clutches one day! Have one of his pencil cases in front of me right now, lovely...
Actually not that many German brands or small designers! But that's
because I never had the money to afford those. I would love to hear some
names if you have them. The last few years I mostly bought on sale or second hand.
I still have a very long list of bookmarks with sustainable brands on my laptop which I haven't accessed for a while, maybe I should take a look.
