Barbara shrugged because she still liked her cape and would continue to implement one into her future redesigns as well, capes worked when you were a bat she supposed. As Dick described the costume he'd worn in the past Barbara couldn't help the delighted grin on her face picturing the teen Dick in something like that, "Oh I can't believe I missed out on that, I can only imagine how much I'd have loved it."
"To be fair, Bruce is a bit of a genius but we were also kids fighting guys with guns and knives, no matter what costumes we had on." Bruce was many things, but practical he wasn't always. She respected the hell out of him, wanted his approval as well, but she knew how it looked from the outside.
Dick had a vendetta against capes, sure Nightwing didn't wear one, but well he was too busy going his own way and she didn't blame him for that, her Dick had never had very intense feelings about capes from what she knew, but maybe they'd just never talked about that. "Yes," She agreed laughing, "I had pants, and sleeves, and boots."
