I see potential of our future but not really how they look.
However, I did improve my first ex's fashion sense by buying him clothes he wouldn't normally buy (my mum also wanted to improve his fashion sense) and he then caught onto fashion a bit more and his fashion sense improved.
My second ex had pretty scruffy, messy hair and he wouldn't cut it right so I went to the hairdressers with him and he told the hairdresser to ask me what I wanted and so I told the hairdresser what need to be done and he liked his hair after it. :) It looked a lot tidier!
My current boyfriend has tidy hair and a great fashion sense so I don't need to make any adjustments. :D
If a guy doesn't want to change his hairstyle or fashion sense though, I won't force him. Both my ex's allowed me to have a choice on what they did with their hair or fashion. :)
Yeah like I'll think to myself "He could be a total hottie if he cut his hair, or got contacts or braces. I won't go out and tell him "You have bad style" or "Get a hair cut", but if he asks I'll politely give him advice without straight up telling him he looks bad.
