Remember those Coclico Adrienne boots I posted yesterday? (I bought them, btw). You said they were casual (which is fine), and now I'm curious to know what makes a bootie -- or any type of footwear -- casual vs. dressy. Please educate me!

Things that I thought made a boot more casual:

- lug sole
- chunky sole
- chunky heel
- wedge heel
- distressed leather or suede
- certain kinds of hardware, like thick tarnished silver or brass zips or studs
- low to mid heel
- slouchy fit

Things that tend to make a boot look dressier:

- patent leather
- highly polished leather
- fine smooth leather
- gold hardware (sometimes)
- delicate heel
- very high heel
- snug or sleek fit.
- leather sole

My new booties are sleek and simple, which feels refined (and thus dressier?) to me, but they are not shiny, which makes them more casual. The heel isn't particularly dressy -- it's a medium height block heel -- but the sole is leather, which is dressier. But there's a thin rubber layer over top of the leather sole, which I makes them practical for day-to-day. So they feel somewhere in between dressy and casual to me. Is this right?
