Heirloom, I saw the picture from Post #723. I know this forum is on shoes, but your whole look is amazing. Your hair is absolutely lovely to me! I learned that a size 43 EU shoe size translates to about 12.5 to 13 American shoe size for women and 10 to 10.5 for men. I comfortably wear a 10.5 US or 11 US shoe. If I was SERIOUSLY ambitious, I'd go to a shoe store or shoe section of a retail store and just try on some feminine shoes to see what shoes would fit me and what I could possibly wear to pair with some of my clothes.
Let me go a bit off-topic for a moment before I get to what I really want to say. I guess from my previous comment, I'm just basically reinforcing that there'd be a number of straight guys who feel they'd get caught dead wearing feminine fashions. It just takes confidence and an eye for style to make any look happen. Like, it takes confidence to sport a pair of feminine heels and make a good look for it.
The one thing I never really think about is some of the reasons (besides fashion) is WHY males wear these feminine heels. I never really think about some of the reasons like (as Heirloom said) adding tension, strength, and lines. I just never really think about how come there perhaps aren't as many hommes who wear these heeled shoes.
