Is it normal to be able to wear like four different sized jeans

Yes. As a guy, I wear anywhere from a 29-32. The darker the jean, the tighter. It has a lot to do with the dye process and the position in which the material is being cut during construction of the garment.

I'm 5'4" and 120 lbs, I wear different sizes of jeans too. It depends on the brand, the fit, and, most of all, the cut. I wear sizes ranging from 4 to 10.

^ same.

It's just the brand. I'm usually a size 9, but in American Eagle, i can fit a 6. It's normal :)

Its definitely normal. I'm 5'2 and weigh 145 I wear all different sizes. Sometimes it also depends what department you shop in. Different stores also use different measuring techniques for fabric. I can wear sizes ranging from 6 to 12. But I ususally wear a 9/10 most of the time.

Yeah it's pretty normal. I own some 2's that fit me but then I can by a pair of 4's and they still fit. It's just every pair of jeans are made differently and have way different fits.

Also you probably don't look as good as you think in all those sizes

Some stores play with your mind and slap a size four label on a true size eight it's a marketing technique. Our society places a high value on being thin so when women think they are smaller than what they are used to, she will be more probe to buy the clothes item. Its a psychological thing. I know a lot of stores do that including express. I learned this in my marketing class it's true!

How fo you guys get thin? I'm 5'10" and no way could I ever get to 130 lbs. I wear a 12, sometimes!!

How did you become a model

I can be a size 4, 6, 8 and 10 depending who makes the jeans, some jeans are cut so well that they can be worn super tight and not show a roll and some have to be a little more loose so there is no muffin top...so at least you're not the only one

Its the brand. I do that too.

I'm the exact same....5'11 and 120lbs and wear 3/4s 5/6 s and even some 7/8s .. I think it's the brand of the jean that determines sizing...every brand is different .
