How short is too short?

*dress & sweater - Jcrew, necklace - Banana Republic, shoes - target

I bought this dress at the beginning of the summer on sale at Jcrew.  I liked the neckline (it has short sleeves also which you can't see) and the fact that it was grey and figured I would get a lot of wear out of it.  Boy was I wrong.

I kept finding that I felt uncomfortable wearing it to work because it is the length that is really skirting the line with too short for the office.  I figured, well, I can wear it in the winter with tights.  Because tights ALWAYS helps the short issue.

This morning I guess I was feeling a little gutsy and hit that point where I was scanning my closet willing something new and fun to pup out at me.  So I decided to give this dress a try.  I wore flats to help balance the length out.  I still like it, though the length is making me a little self conscious.  However, I now know that I will be wearing this dress in the fall and winter with colored tights... because you know how much I love colored tights! :)
