I have one lying around but I never wear it...
I'm a messy cook and I do get splattered etc but since I'm not usually wearing any fancy clothes, I don't bother wearing it.
How do you feel about apron's symbolism? (i.e. that women are supposed to stay in the kitchen) When I thought of this topic, it reminded me of the time we were discussing gender roles in one of my classes at school.
I don't think it's common nowadays for women to wear aprons maybe because a lot of them are juggling career and housework, multi-tasking etc.
