Karate uniform and belt size help xP?

Sounds like you train at a school that does not care about the students. I have heard this same kind of problem many times. Some martial arts schools will stock a few uniforms and belts. Then when someone needs on they will try to pawn off what ever size they have on them. It speaks badly of the school you train at. Any self respecting instructor does not want his students tripping on a uniform that is way to big. He also does not want the students to look sloppy. I'd suggest you buy your own uniform and belt. When you do be sure to go by the size chart used by the brand you are buying. Uniforms from different companies are not all the same. A Size 3 in one brand might be bigger or smaller. Other than that I'd step back and take a serious look at the school, instructor, and school you are training at. It might be that you should consider going to a different school to train. something is wrong there.
