Fashion ? about over the knee boots

[heatherjax]

I have been noticing that over the knee boots are very in right now and I considering getting a pair. I have a pair picked out, the heel is not too tall. I'm 23 and I will mostly wear them going out with by boyfriend and such. However, can I get away with wearing them to work? I work in an advertising agency and would wear them with longer skirts past the knee so most of the boot would not show anyway. There are plenty of co-workers you wear boots, but none I think are over the knee or at least none that I've noticed. Thoughts anyone? I want these boots bad and don't want to have to buy another pair of knee boots too.
