Iz there a way to keep my older sister out of my stuff?

Asking her iz never enough and telling her is never going to happen......but she went through my stuff.....and I mean stuff that I wanted to keep hidden from the family......she wanted some of my body spray and she found something that I didnt want people to see......and im sick and tired of her doing this to me all the time( and she takes my socks ) is there some kind of way for her to stop doing this
