Well I'm not exactly Thumbelina and I like wearing heels. 1m75 and up would still be acceptable I guess, but he'd really have to be the perfect man for the rest.
Some people tell me it's a conventional mindset, created by society, but I read that it's biological and that women look for a man who is about 1,09 times taller than they are. True story.
For me, that's about 1m85.
I'm not short either and I also love wearing high heels. My fiancé is about the same height as me and I think he is just perfect.
Of course, when I'm wearing high heels he is shorter than me but I think it is sooooo divine.
