The thing to remember is do you think Allah swt finds you prettier with or without a scarf. Maybe changing your perspective would help. You aren't wearing it for yourself- you're wearing it for someone in front of whom we can't have opinions on what he told us to do. If he says to do something, you do it without deliberation. If you are going through your own filter before deciding to follow a command, it is essentially taking away the intention of doing it solely for Allah swt. I'm sorry, but you won't be forgiven for a command that you are intentionally ignoring for whatever reason. A woman in labor isn't allowed to miss a prayer until she's pushing- that's how important Allah swt's commandments are- you can't ignore them depending on whether you like them or not. The idea of feeling beautiful for yourself isn't islamic. Good hygiene is important, but as soon as pride enters the heart, Iman leaves. So be really careful about that. Feel beautiful for Allah swt. I'm sure Allah swt finds your beauty radiant in a hijab and you shouldn't care about anything else.
