Jeans dilemma

Im using jeans bigger than my size cus I hate that jeans my size look too tight like u can see the shape of my leg and that freaks me out. I don't think I have specially big legs but they’re a bit muscled. But now these jeans are starting to be 2 big to me cus im losing weight, so I don’t understand my sizes anymore and I want to kms. Joke I don’t but dammit. I could use a belt yeah but I don’t have one my size now cus the only one I had was from my father and now it doesn’t tightens enough 4 me. Anyways who cares, baii :p
