I'm all about the black patent leather.. when I was in the service I had to wear black patent shoes with my class A uniform. it was a bitch getting that spit polish mirror shine but they looked classy. In a womans heels, it's classy and sexy.
The red or the burgundy are amazing choices. Those would be my first choice, my second would be black. My least favorites would be the nude color, because although they're more classic and low-profile, they're at the same time the once more prone to show a dent, scratch or stain.
I work in a second hand luxury products e-commerce, and all the nude colored shoes we get are really a tragedy. Speaking of which, second hand sites like The Real Real or others could be a good option if you want to try shoes at a way smaller price and look just as amazing.
I'm not personally into heels, but even I understand that Louboutins are some exquisite pieces.
Black is very classic, functional, dependable, and stunning; it would be a good first pair. Otherwise, nude is also a good option. The others listed are more "repeat" buys, if that makes any sense-- a return customer.
I would love to be able to hear heels like that. Unfortunately I am already as talk as a bean stalk so I don't get that luxury. I love the black or the red patent. I love shiny shoes. I'm kinda leaning towards the red more though.
