The jumper and the sweatpants-looking- trousers are both from "Opus" they have beautiful clothing! I don't like wearing too shiny, too bright clothes, so their store is just perfect to me. I'm obsessed with the trousers! Since I'm in love with nude/brownish colors lately, I thought why not combining them with a warm color. I looked at their online store and couldn't find the same trousers, but something very much similar to it: https://www.casual-fashion.com/en_de/opus/trousers/cloth-trousers/smart-trousers-melosa-grey-sensible-grey
If you like to feel comfy but still wanna look fashionable, you should definitely have a look at this! I can't wait to combine them with more classy pieces.
