7. Green Arrow

I was a little hesitant when the show first started but I have nothing but love for the Green Arrow suit.

It adopted the hood and jacket thing from Smallville's Green Arrow but gave him a mask and a bit more subtle of a super suit. I've always been partial to the goatee and Robin Hood hat version but hooded Green Arrow is a time honored tradition and I will respect it. And even goatee-less, Amell has more than made the character his own over the years. The color palate is a little muted, but that works and is even necessary for the tone of the show.

A neon green parka would have stuck out like a sore thumb in a healthy thumb convention. The costumers for the Berlanti stable of DC shows have only gotten better and more confident in their designs as time has gone on and I feel their work goes unappreciated by the masses. As a tone-setter for the entire universe, this costume kills. It establishes an aesthetic that would go on to influence every other costume on this list.

Talk about a good first impression.
