Women: When you get married, do you have to wear your wedding band or can you continue to use your engagement ring?

I’ve never been into jewelry and when I do wear it, I like small, simple things. I recently got engaged and was thinking about just wearing my engagement even after I marry. I just don’t like bulky rings. I like skinny, small, little rings. Wedding bands are usually too thick and I’ve never seen one that I actually like.

Do any of you do this or am I a little crazy here?
