Last minute cosplay ideas?

[yukimizu]

So I was a total idiot this year. I had some cosplays planned, but then I didn't think I'd be going to Kumoricon, so I never worked on them. And now that the con is THIS WEEKEND, (LOL) I have NO cosplays to wear, so I'm totally looking for something I can either quickly whip up in the next few days(mind you I'm terrible at sewing, but I manage), or something I can buy from thrift stores.
So, here's a pic of what I look like..

My body type is NOT thin, or leggy. So most revealing cosplays will be an immediate NO.
And any ideas are seriously loved. I have a few wigs, so they could come in handy too.
(my wigs are all straight styles 1) short black with bangs, 2) long brunette without bangs, 3) long pink with bangs, 4) medium lenth yellow with bangs, 5) sailor moon styled blond wig, and various cheap halloween costume wigs..)

Thanking you all in advance for any ideas you can offer!!

White long-sleeved dress shirt, big black glasses or frames, brown vest, red tie, black knee-length skirt, skin-colored nylons and black flats. Add some pieces of paper and a book or three, and you're set.
