Officially, Sin City: A Dame to Kill For. For the younger generation, the word 'dame' is what you used to call a girl when you had to take off five layers of her clothes just to get to her bush. Yes, I know, they had those too back then. Either way, Sin City 2 has Jessica Alba in not many clothes, which makes it an instant must-see flick this summer.
You can check out snapshots of Jessica Alba showing off in her bra in Sin City 2 on WWTDD.
