The sleeves should rest right above the top of your wrist. Sometimes you want the style when the underlayer sleeves are slightly visible in the end. In that case, you can go for the sleeves that end at the hinge of your wrist. However, that is for formals or business casual looks. For a regular outfit, you may want to cover the underlayer sleeves completely unless you are rolling your sleeves. Even if you are buying baggy clothes, your sleeves should be the right size.
