I'm just really mad right now. :mad:
First of all, my sister (5 years older then me, now 18. I'm 14) orginially never fit in my clothes, but after losing 25pounds, now she can.
She also thinks I'm an immature, spoiled brat. I'm sure most older sisters think of their younger ones this way. {masked profanity removed-<>}
I don't have much in the first place. 6 pairs of jeans, a few hoodies, tshirts. Just enough to suffice through my teenage life.

First of all, she has access to all my clothes because she took over my room this summer when she came back from university (yes, originally her room, but once she left, I moved in). She has turned into a complete pigsty. I kept 'her' room neat and tidy (not pristine, but nice and neat) and now its clothes (MY clothes... ) strewn everywhere with garbage and half eaten food on my clothing.
She wears only my clothes to work (I don't really mind that, I don't need them for now) and comes back and throws them on the floor everywhere. She wears my socks too. I don't have a single matched pair now.

She also complains that I have too many clothes. She says "I'm taking all your clothes with me when I leave okay?".
Of course, I say no. But she retorts "You like shopping so much, you can buy new clothes".
Sure, that sounds fine-dandy, but I LOVE MY CLOTHES. Everyone of them. I only buy the most fitted jeans for me and my hoodies are all warm and comfy. I take care of them well, keeping them odour, wrinkle, and stain free. I barely need to wash them, since washing them ruins them.

I decided to strike a deal with her. I said I'd give her some of my hoodies. SOme of the less-loved ones. But I say "You can't take my jeans".
Her retort? "Too Bad".
I've been completely serious too. I stamp my foot, and look down at her.
Her retort is still "Too bad."

I swear, she's being an idiot right now. I don't mind her taking clothes as long as I can still find them and wear them again. But she's taking them to university with her. I'll never see them again. I'd never get to wear them again till she comes back. Also, I'm not being selfish. She's taking them away and I'll never see them again. I'm pretty sure that's considered stealing, not borrowing/sharing.

She did it already. I looked everywhere for my brown stripe hoodie. Three weeks after giving up, she came home for the weekend, wearing it. I got so mad.
Her excuse for taking is still "You like shopping right? You can go buy more" (I actually don't shop that much, it's just since she's come home, I've gone shopping a lot for back-to-school. I'm going to high school, so my mom thinks I need new clothes).

So, I'm just venting. But, any advice would be helpful. I have a lock on this room that I am using right now, and have taken ALL THE clothes I can find and put them in here, but I can't lock the door at night and that's when she comes to take my clothes. Plus, she's already taken 2 pairs of jeans.
I'm pretty ticked off right now. I just want her to not my clothes away.

First, you need to watch the language. Even masked profanity is not allowed here.

Second, where are your parents in all this?

That's what I'M wondering.

I say tell your mom.

If she is allowing this, then there has to be a good reason.

Sorry to be so harsh, but it sounds to me like you're being a typical teenager. Immature, unappreciative of what you have, and self centered. Sorry, but it's what you sound like.

I'm sure it's not as bad as you try to make it seem, and you're overreacting.
(Reddie for harshness? Eeh, it's my opinion.)

Seriously, you can't possibly live alone, or with your sister (since she spends her time at a university) so your parents should be on top of this.

Talk to your parents about this!
Also if she moved out of that room maybe talk to your parents and say that when she comes back she should go into the room that you left because it is not fair! She moved out which means no take backs!!
If I had a sister there would be no way I would be sharing any of my precious clothing with her especially if she treated them in the horrible condition you are speaking of!

I would seriously get my mom involved in all of this, And lock her behind out of my room anyway. Your belongings belong to you. You're being generous enough to let her wear them when she's home. Tell her to buy her own Dang clothes. I'd be pissed. Or heck, take some of her things. Or take your things back. I don't think you're being immature at all, she is.

Tell your mom & its YOUR clothes so tell your sister she's NOT touching it. If she takes it go in her luggage and take them out and say too bad there mine.thats what I would do.

I would be hiding them and tell your mom.
