Love Barty :)

This was really funny, cute and entertaining.
I really liked the fact that Barty is such a cutiepie in this one, he's like that loud, obnoxious, inappropriate friend who we hate to love.
I never thought of this pairing though, it's interesting to imagine how this dynamic would be in the actual series.
Well done!

Well, this is different. I've never read about these three together before. Nor have I read about them in a Muggle!AU. Quite the unique pairing, since I usually only see Hermione/Severus.

Mr. Snap. That's funny. It reminds me of a snap pea.:P

Barry's cute in this, telling her she ought to wear a sexy nightie, then sounding disappointed when she tells him she won't be wearing that. You made me love the Hermione/Barty pairing with that scene.

Haha the end where Severus just kisses her was delicious. I'm surprised he did it but I guess Barty's suggestion was definitely an improvement. I don't really see the three-some pairing here, since Barty doesn't really anything explicitly romantic/sexual except suggest she wear a nightie (which a very loud and obnoxious friend might do).
Other than that, this was well-written and an entertaining read. Good job.

:D This was wonderful, I certainly chuckled at their antics. Lovely AU :) xx

[since she had already taken the cap off...] - This bit of information seems extraneous and makes the sentence clunky, in my opinion.

Hermione struggling to put on lipstick correctly! Well, now, there's one thing I never imagined her having an issue with, but I think it's a cute idea.

[Glancing back at the mirror]...[When she looked to the mirror] - This seemed weird to me. She just looked in one mirror. Why is she looking in another? With the second time she looks, you make it sound like it's the first time she's looking.

[It's not. Turn the TV back on.] - Love this line! It's cute and so Snape. Although, TV is usually capitalized.

Snape kissed her? That seems pretty OOC, and I was a bit confused about it at first. I assumed it was Barty (which I supposed wound be something he would do with the way you've portrayed him), but I wouldn't expect something so forward from Snape, even in an AU. Hermione at the end seemed way OOC, too.

I have to admit that I'm a bit confused, though. I'm not sure why these three particular characters are living together or what's going on at all. It was a cute one-shot, but I almost feel like part of its impact was lost on me, personally, because I couldn't get past the confusion about the characters and the way they were acting. I think I almost would've just liked to see Hermione and two OCs or Barty and two OCs.

SPaG:
[the people at studio] - the studio?

Hermione in a lipstick commercial, lol. Considering how much she doesn't care about her appearance in canon, this comes off as being pretty comical.

Is flavored lipstick actually a thing? (I know almost nothing about makeup.)

Barty was being quite the jerk here, and although Snape was also teasing her, he was surprisingly sweet.

I didn't spot any typos or grammar issues. (I did think "Mr. Snap" was a typo at first but the next line said it was a nickname...)

Flavor of lipstick? Shouldn't it be color? Lipstick isn't usually flavored.

Hermione as a model/actress is weird since she was always described as being so physically unattractive in the books. I knoew thi is an AU but Hermione and Snape both seem really out of character.

Oh so the lipstick was flavored after all.

The relationship between the three characters was never really explained. Were they supposed to be in a relationship with each other or just room mates?

Petit OS plein d'humour...
Hermione n'a pas obtenu l'approbation qu'elle attendait avec Barty et Severus
