So just a refresher..
Kathy and Sabrina are the most unlikely of BFFs, even though at first glace they look odd together because
A.) Kathy is the uplifting, cheerful, quirky girl
B.) Sabrina is the goth, dark, and evil girl.

But when you see them more often, they aren't as different as they seem.

Sabrina actually doesn't mind wearing pink and white NORMALLY. Kathy changed that about her.
And Kathy looks good in black clothing, all thanks to Sabrina and her wardrobe (she makes her own outfits BTW, and they're, get this, goth clothing XD). Before, she thought that it wouldn't look good on her.

So. I did some messing around and made the closest pictures of the girls I can get.
Here is Kathy:

And here's Sabrina: (SHE'S WEARING A TAD BIT OF PINK SO DON'T FREAK OUT!)

They originally met in 3rd grade, as I established in Sabrina's origins. Sabrina saved Kathy from a 7th grader and those two have just stuck together ever since. Now I know some of you are drawing parallels and similarities to some of your OCs by now but it's not intentional.

They both work at the new Maid Cafe (Aphmau fans know what I'm talking about >:3). They were transfered temporarily while the old cafe was getting repairs.. The maid cafe was a "sister location" to the old one, but it was on the other side of town...? Yeah.. And both have to wear uniforms :3

To all you prevents out there (*COUGH* ARES *COUGH*) yes they are wearing somewhat short skirts but I'd beware of them of I were you, they were cheerleaders once.. (Kathy forced Sabrina to join with her because she didn't want to feel lonely.)

I really don't know what else to put other than they have "girls' night" once a month with Clockwork, McKenzie, and Nurse Ann at Kathy's place. When her parents aren't home of course. XD
