Keep in mind that Kumi usually wears very tall high heels. I remember in one of those variety shows she was standing next to a guy, and then she took her shoes off and went from pretty much his height to his shoulder. lol
Also, there is this legendary picture of her with Rihanna, which is 1.73m and is not even standing properly.
I feel bad for not enjoying MY NAME IS... Tour as much as I would like to, even tho it's now the concert I have watched the most probably, because of the different dates streams.
