Free People Sundown Pumps

I bought these Free People Pumps here on Poshmark but they are a size too small. The listing said they were a 7 but they are a 6. I only wore them once for a couple hours at a bridal shower, mostly sitting because my feet hurt since they are too small for me. The original listing said they were only worn a couple times. They have some normal wear and a nic on one heel, as pictured. They are a eu size 36. One heel says 37 and the 7 is crossed out... but they are the same size.
