H&M Iridescent and White Slides

PLEASE MESSAGE BEFORE BUYING These slides are SO cute! Perfect for the beach or just running errands. The iridescence makes it shine and change color when you walk! It's super comfortable since the bottom of the slides have curves that fit your feet! They have only been worn 2-3 times and are basically new! I ONLY HAVE 1 BUT I AM LISTING AS MULTIPLE BECAUSE I THINK IT CAN FIT A 7/7.5 (my size) BUT THE SLIDES SAY 38/39 (which according to poshmark is size 8) They are approximately 26 cm
