Loly in the Sky Ariana heels

Elegant retro style Loly in the Sky brand Ariana heels. Only worn in the house and garage port. Brand new. They say they are size 23 1/2 in Mexican sizes., But I wear a size 5 or 5 1/2 in heels and These heels were only slightly too big for me. I’m guessing they are a size 6.
