Okay why is my little sister dressing like a whore she wears like eyeliner now and mascara and every morning she straightens her hair wears big bras tight clothing has boyfriends and acts like shes a teenager or somethin she is 12?

She probably wants to look older I think you should have a chat with your sister and tell her what you think so that people wont go and say it to her and upset her its better you tell her than someone saying horrible things to her.

I don't know why your sister is choosing to act like this, hun. But think about it- you're her big sister, and no matter what, she looks up to you. Talk to her about it, she'll probably respect what you're saying. My big sisters mean the world to me, and if they told me that what I was doing was inappropriate for my age, I'd stop and change what I was doing. Just let her know what you think. :)

My sister's the exact same. It's so annoying because it seems like she's trying to be like her friends, Well, one of her friends at least. My sister wears bras that are way too big, (and it's obvious) and tight shirts. And today she was wearing short shorts, and oddly enough, her friend was wearing the same thing -.-

Puberty she is looking like WATS in fashion girls look like that to get a bf

I do the same thing except without the makeup and the tight shirts or big bra  also I don't do it for boys and you sister might feel a little uncomfortable so try to change her mind .. About what shes wearing

You need to talk to her. She's going to get potential unwanted attention from older men.

Trust me they all do that, its a phase. That's all there is. Just hope she gets over herself soon. :DD

How does her big sis act and dress? Stop and think where is she getting this at? Is it the other kids she is hanging with? If you lead by exampl she sould follow!

If   someone doesnt  control  her she  will  continue  to head  down the
wrong  road  , Maybe  next  year  this  time  she may  end  up  pregnant
where  is  the  adult  supervision  with her , If  people  have kids  and can't
control  them  than  they  should  place  them some place  to get help
before  it  gets  too  late , sounds like  she really  does need  someone to
say hey  your  the  child  , I am the adult  here

It is called the negative effect society has on people, for example look at all the people trying to be a big gangster like lil wayne, but soon enough they will realize that their role models aren't the best role models as even though they are rolling in dough. "they would choose to wear meat, while we still have children out starving on the street", anyways I have found old school rap to be the best cure for this.

Simple reason why is because of you being older she wants to act the same age and just say look my friend got me this top , you should get one like it , its lush! And then she wont attrack any unwanted attention x and the bras just say it seems to be sagging why not try this one? X

That's what pre teens do my friend does that it's just a phase
