too costumey?

Last night I swung by a Goodwill a few miles from campus.  I fell in love with this plaid skirt with an asymetrical hem by Cato.

But I wonder if it is too costume like......do I look like I am going to some Highland games?  Maybe a different styling would help.  I did try it with my new olive green cashmere wrap sweater, but I thought this look was a better shape on me.   I thought about my cream turtleneck sweater, but it is in the hamper waiting for a wash.  The cardigan is Target (new with tags) via Goodwill.  Seriously, I should become a spokesperson for Goodwill.
