help with finding clothes in Europe ( eastern part)

Hi everyone<3!! I live in eastern part of Europe(Poland if be specific) and I have a problem with finding clothes:(

I usually buy my clothes at thrift stores but recently I can't find anything and most of the good thrift stores are a little too expensive TvT

Do you recommend any shops/alternatives? Tips also will help!! :3

Also sorry if I made any mistakes, it's my first time speaking anywhere + I don't realy know how spacehey works:")

Have a good day/night!!! <333
