It seems to be a Japanese size 24~24.5cm. My usual shoe size is 24cm or 24.5cm, so I bought these cabaret heels in that size. When I tried them on, they were too tight for me, so I think they would fit perfectly for someone who usually buys one size larger shoes! By the way, I bought a shoe one size larger and it was a good fit! These shoes seem to be popular, and many sizes were sold out! I also thought they were the cutest shoes I've ever bought, but unfortunately, I couldn't wear them... Someone please wear these cute shoes for me (;_;) Also, there are spare black heel tips! I'm also selling a dress, and I'll give a little discount to those who buy the set ( . .)"
