Reddit mentions of Top Moda Womens Pure-65 Mid Calf Round Toe Slouched Wedge Heel Boots,Black,8

I did this same costume for Dragoncon this year.

Wig - I did a wig one day and my natural hair the other days. I prefered my natural hair to the "widow wig" I did take the wig in and have my hair dyed to match so that the red was right but seriously, go with any length hair you want.
Boots - Any combat type boots work well. I went with the below because of the buckles and wedge heel. http://www.amazon.com/gp/product/B00KR7IAXU/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

Belt - I bought a large belt from goodwill, covered it in the same fabric as the cat suit (friend sewed it for me so we had scraps) and used oven bake clay to make the widow buckle.

Guns/holsters - here it is a matter of how much $$$ you want to spend. She uses Glocks where are near impossible to by airsoft versions of. It is also near impossible to buy cheap airsofts that look right AND fit in a left handed holster. I take cosplay seriously so I forked out the money. Best bet.. go to your largest area airsoft dealer with pics and see what you can find in your budget.

Holster. I made mine so that I could fit it properly. I did fork out the money for the actual buckles she used but they are spendy. A plain craft store buckle should be fine.

Gloves - Good luck. I managed to find the perfect match motorcycle gloves but they were a size to small and dyed white. Most places were out of stock of the white versions as well. I re-died them black with the help of a friend and cut of the fingers. I still need help getting them off as they are so snug. Best bet, look for cheap motorcycle gloves in your price point.

Stingers - Of all the widows I talked to at dragoncon these were the things people complained about the most. Many used a cheap plastic bandolier like http://www.amazon.com/gp/product/B0026KR6HC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 but then you have to glue and paint as the pieces fall apart easier. I used nurf gun bullets that I painted and sewed onto elastic but they didn't hold the paint well and I had to do a lot of touch up with black nail polish during the con. I wish i had gone with my first impression and made them from oven bake clay as well.

Overall. Don't worry to much about the details. NO ONE is going to be looking to closely at the details. As we like to say "There are no inspecty thingys." The bigger the group the more forgiving the audience is as well.

Good luck and have fun!
