Ms. Fanservice/Web Original

"Harley: We all know that no one wants to see a douchebag eat a corndog, so we brought a little girl in for all you perverts!"
 * Sarah from Lonelygirl15 is a relatively mild example, but it's blatant enough that fans have been known to nickname her after her breasts, or even jokingly treat them as a separate character.
 * While Codex and Tinkerballa of The Guild dress quite normally, their avatars... are another story
 * Taylor Amelia, a talented web comedienne whose videos nonetheless focus on her other incredible "talents".
 * Samus, from There Will Be Brawl.
 * Lt. Lisa Foiles from The Angry Joe Show. She went on a rant and her uniform started falling apart.
 * Link, please?
 * 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". Just look at the "Nintendo Controller" tanktop she made and you may agree with me that the woman is deliberately TAUNTING us.
 * 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.
 * While this isn't what she's like normally, The Nostalgia Chick had this role in That Jewish Guy's "Eight Myths About Hanukkah" video, where she looked incredibly dolled up. Now that's a Big Lipped Alligator Moment nobody's complaining about.
 * And let's not forget her outfit in Linking with Linkara.
 * Jillian Zurawski, aka Mrs. Cinema Snob. Brad loves to show off her assets.
 * The girl from EPICMEALTIME's Massive Meat Log:

"Narto: Yeah. As I said, she makes a very nice elf.
 * They use another girl for Fast Food Sushi, and then they both come back for The Black Legend.
 * Protectors of the Plot Continuum Agent Louise becomes this when they land in the water, and she's Going Commando in a white top.

I was polite, though, and didn't stare. "Ah, Louise," I said, "your top… uh…""
