oh...oh my good lord. haha.
let's see. i'm making some guesses here, but i would say i have around 70 - 100 pairs of shoes. about 20% sneakers, 20% boots, 50% heels, 10% flat sandals/flip flops/flats. i only have like, one pair of ballet flats, and they're the foldable kind for when my heels start to hurt.
i think i have an absurd amount of heels considering i work from home. but yeah. i would say about 75% "summer" shoes, 25% "winter/fall" shoes (i live in southern california). that said, i don't wear all my shoes all the time -- i do have a few that i wear on a regular basis:
sneakers - i love sneakers and i wear them all the time. for non-running sneakers, i have a neutral-ish pair of zanotti high tops and a sparkly pair of crystal-studded gucci high tops. for low-top sneakers, i rotate between these pink miu miu sneakers and these navy miu miu sneakers.
boots - despite living in southern california, i love knee-high boots. these donald j pliner devi3 boots are my favorite; i wear these black gucci riding boots when i need something dressier. ankle boots - i love acne's pistol boot.
heels - i have a pair of black patent louboutin new simples as my staple pump, i have a bunch of ridiculous heels but go-to "event" heels are either the jimmy choo greta sandals or the gold ysl tributes because they're so comfortable.
as for must-have colors and style, i tend to go for metallics and crystals (as you can probably tell) and black. i think a nice, dressy sneaker is a must-have because you can dress up an outfit SUPER COMFORTABLY and still look totally on point.
