Who says that being an ass-whupping Action Girl means you can't wear feminine, pretty, opulent clothes? In some works, the two can go hand-in-awesome-but-elegant-hand.
There's hardly any Action Dress Ripping either. These are Impossibly Cool Clothes that don't get in the way while this lady is mowing down hordes of mooks or blowing stuff up. Conversely, she is such a good fighter that she is both aware of and able to overcome the disadvantages of her clothing. Not that there can't be Clothing Damage, but expect the clothes to be fine by the next episode (barring getting a new outfit next season).
