Erima is a German company (that’s been around for 115 years!!) They have affordable high quality workout clothes. In all kinds of colours, they are often used as kits for a specific team or club, but of course you can also just buy it for yourself.
Decathlon is French, so that’s an option as well.
I really love Doechii, especially “Denial is a river”. But her whole most recent mixtape is amazing. Also do checkout her Tiny Desk performance, she is the one to watch I think.
