Swaaaaanky, so good to see you here. Yes, get started on that collection right away lady. Here is my recommendation:
Black Pigalle 70s
Nude patent Yoyo 85s
Any color in the Very Prives (covered platforms) should be your 3rd pair. They have the 70mm, but I believe you will be prepared for the 4.5 inchers by then. lol They are gorgeous!
