As a teen it was a bigger issue, i have been 5' 9" since i was 8, but as I got older it became less of an issue, however one of my exs complained if i wore heels because that made me tower over him. My man is 6'4" and I have to admit it is nice to be able to wear my heels and be face to face.
I think the biggest thing here is we don't know this relationship.
From my own experience I am always more dressed up than my man, I like to dress up for myself. I also know that if it is a special occasion he will make an effort for me, so on other occasions I am fine with whatever he choses to wear. To me there are just some things more important than apperance: honesty, kindness, humour, intelligence, endurance.
