Thrift shopping can be awesome, you can find so many unique things. But you definitely need to take your time, at least an hour or so to be able to look through all the blazers, shirts and so on. I usually spend about an hour and a half or two. Another thing to think about is make sure you wear comfortable cloths and shoes, so much easier to try on things. Depending on where you go but most thrift stores or even Goodwill stores are kinda dirty in the dressing room so be aware of that. I personally love thrift shopping, I usually go every second week or so to check out and see if they have anything new.
I bought many blazers like you can see, some blouses and shirts. I really wanted to show everything but I haven't washed some of the stuff yet, got some new blazers yesterday but I'll show the rest next time :)
