We often see the heroes in the Marvel Studios movie get new costumes or little tweaks. Scarlett Johansson's Black Widow got some cool Tron-esque accents on her costume. Going 'electric' came in handy with her Widow sting blasts. While Johansson might have had to carry a large battery pack during filming, this shirt is less cumbersome.

ThinkGeek has come up with a light up Black Widow t-shirt. It's a quarter-zip fitted tee with blue electroluminescent wire and an Avengers logo on the right shoulder.

How does it light up? It does have a battery compartment and requires two AA batteries. The battery pack is said to weigh about the same as a large belt buckle. The shirt is also washable so you won't have to worry about any superhero battle grime that might get on it.

This is a ThinkGeek exclusive and costs $49.99. You can find more information HERE.

What do you think?

So they're finally putting out Widow merch.

Hot chick.

I don't care if it's for girls; I'm getting this.

Sweet! I'd totally buy this.

thinkgeek has the best merchandise

Makes a good Halloween costume

Why don't they make this is full-figured male sizes?!

This doesn't look that good, don't know why you want to buy it. I don't see anyone wearing it any day other than halloween. It would just be sitting in your closet for years, unless you use it as a lamp. Also pretty expensive

I wonder how many people will mistake it for Tron at first glance.

On the whole, meh. But since I'm a guy, I'm not the target audience, so it doesn't matter.

Ugly shirt!!!

Grayson cosplay

Impressive
