When I was a kid used to get upset I couldn't wear a dress
That's strange. Why'd that upset you so much?
I think it's just because I have always liked to wear dresses
You enjoy wearing dresses to express yourself, I bet.  There's nothing wrong with that and it's totally okay to be a little upset when people prevent you from expressing yourself in the manner you'd like.
Even though I have one now, I don't have time to wear it.
That's perfectly fine, too because you now have the freedom and choice to wear it whenever you want! You deserve to express the way you dress to make up for what you couldn't do. You were rightfully upset, and I hope you have all the dresses you want now.
