I love genocide. I just wish there was some way I could actually vote for it. Instead I’m stuck voting for the closest option which does none of what I want but fortunately both sides support Israel killing Muslims in mass.
I’ll put this here because people are dumb as hell /s
Gustin has some good stuff sort of like you are looking for. Their fits run a bit small/thin compared to sizes in the US not sure about compared to European size comparisons. I have a ton of plain Ts and sweaters from them I adore. Good quality not real branding. Some of the sweaters I bought are 6-8 years old at this point and still in great shape.
Most of their stuff is a bit too pricey (for my taste anyway), but if you find multi-packs of the shirts and sweaters it’s more reasonable. Like these:
