My group of friends obsessed with brands and my LCW dress

So girls, I’ve joined a new friend group and they all dress super brand-heavy, everything is basically logo. I wore a dress I bought from LCW when meeting up with them yesterday, but honestly, I felt really self-conscious. No one said anything, but I couldn’t tell if it was just me feeling that way from their looks. Do you think everything has to be brand-name to fit into a group?
