I went back and checked. In the low forties I think for tops and dresses. Nearly up there with Jenni! I am quite a dress liker
My count included special events (2-3), loungewear (3-4) and a dress I only wear occasionally when my weight is low. It also included 3 black tees I bought about 10 years ago. I bought one replacement 2 or 3 years ago but it hasn't worn as well as the older ones.
My aim in general is to only buy as much as will wear out in the time that I want to wear it. Like you and others, this inevitably means that I have to buy only a small number. Possibly unlike you, I've come at in from another pathway - I'm not a wear tracker. I just limited myself to, eg one casual sweater a year, (usually) one pair of jeans etc.
My handed down items swell the ranks though. (at least 3 of the dresses) Because they aren't chosen by me, they tend to be less versatile. Conversely though, they are often of my higher quality than I would have bought.
Anyway, just riffing on the theme!
