My boyfriend asked me if I could wear something he liked?

So I’m visiting my boyfriend tomorrow and he asked (not told/ordered) me if I could wear this blue dress he saw me wearing the other day in a picture. His exact words were “If I may ask, could you wear that blue dress I saw you in that picture the other day?” He said I looked very cute and wanted to see me in it. It did catch me slightly off guard and I know some people try to control what their partners wear, however it seems more of like he’s asking me for a favor. Is this normal/okay?
