Lt. Lisa Foiles from The Angry Joe Show. She went on a rant and her uniform started falling apart.
Not to say she's conceited or anything, but Lisa seems to be fully aware of the fact that she's... visually pleasing and isn't afraid to flaunt it. Just get a look at Episode 3 of her "Everyday Achievements" series or her video with Angry Joe from E3 where the caption underneath reads "Hot Chick".
She displayed awareness of this fact in her top 5 best moments of Monkey Island, pointing out she wears tight clothing while wearing tight clothing. The comments section on the Escapist were really... happy about it.
Invoking the trope Evil Is Sexy is the main villain, Cinder Fall. She waltzes around in a slinky red dress that shows off her legs and her shoulders, not to mention the attention bestowed upon her by the camera in this scene, ◊. It doesn't exactly hurt that she has a very sultry voice courtesy of real life Ms Fanservice Jessica Nigri.
Post-Time Skip in Volume 4, Weiss falls into this. The camera makes sure to take a lot of lingering shots of her nice, long legs.
Screen Team has Angie Griffin, comedic partner and wife of Chad Nikolaus. She's certainly not shy about her assets, as a lot of their videos show her wearing some very low-cut costumes. Here's their page. Better clear you schedule.
Parodied with Kurokawa from Senpai Club. She literally always has her panties showing and her breasts are prone to giggling,
