Slutty or Not?

So I'm going to Sarge's squadron's Christmas party this year. That means I have to dress in something other than jeans and sneakers. Bah.

I'm looking for a pair of heels, and kind of want to get these. Yeah, yeah, they're from Frederick's of Hollywood, but that was pretty much the only place I could find them within my price range, I don't want to spend more than $40.00 for a pair of shoes I'll only wear about 2x a year. But I like the heavy ankle strap look.

So the question is, are they too slutty? And are they AA(Age Appropriate)?

I will be pairing them with a pretty conservative skirt and blouse, what I might call, "Stealth Slutty".
