Here's mine, from last October (week before Halloween) at a local comic book shop.
And another shot (minus the coat) at another event, the week prior.
Total cost for my costume was around $30 + cost of make up.
Make up was done by me and took nearly an hour each time. (top pic, I know, it goes up too far)
Every piece was mostly purchased at thrift stores around town.
I was lucky enough to find an actual long purple coat for only $10.
The hexagon-patterned shirt $3 by Tripp.
The tie I bought the year before $3. (Closest I could find w/ out breaking the bank, LOL)
The pinstriped slacks $5.
Shoes are my own from work.
"Pocket" Chain $2 (Home Depot) 3 feet total.
The gloves are from Party City, painted w/ diluted purple fabric paint. $3.
The vest I painted w/ green fabric paint $3.
Bought a different vest that I will use this year, and will paint a darker green.
Didn't get any pics from Halloween Night, but I will this year.
Both pics from my Deviant Art account.
