Advice!!

I’m ready to purchase my first pair of red bottoms!!
Should I get the classic so kate’s or miss z’s?
Also should i buy from the brand store or a reseller?

I heard miss z are easier to walk in, is that true?
I want to visit the store but i’m afraid of being treated unfairly and ruining my experience, it is a big dream of mine i dont want to taint it.
Should i make appt or walk in?
