The best thrifting tip I can give you is that you’ve got to go OFTEN!
I went on Thursday and spent way WAY too long trying on all the pants and jeans in my size (I really need a new pair!). Since I had no luck there, I made sure to also check all the shoes and skirts and even a trip through the jackets and blouses. Yes, pretty much the whole store.
This cream and gold bubble skirt was a dream, just not for me. And the gorgeous electric blue velvet blazer had a couple of noticeable stains, so no thanks.
Luckily I did not go away empty handed, this little white skirt will be perfect as an under skirt to show off the lace trim and the sparkly top is a fun dressy piece. Someone had dropped off as HUGE amount of costume and 80s jewelry, all I really had to have were these bright blue earrings, and I got this single (searched for the twin) fan earring for 50 cents. Total spent $12.50.
After such a hugely stressful (oh yes it was) shopping excursion I would normally wait a while to go back to the same store, but 5 days later something was pulling me in. After a couple laps I found these two killer belts. Yes, you can have my six dollars.
So the moral of the story, check back often as stock changes daily.
