I want to wear the same dress everyday - 3 years and 4 months

This morning, Lexi had a melt down. The reason is she insisted on wearing the same pink dress that she already worn yesterday. I tried to talk her out of the idea. 

First I told her she already wore it yesterday, and people don't wear the same clothes for two straight days. At 3 years old, children don't care about what others think of them. and I don't want her to care too much about what others think of her either, so I didn't try to persuade her with this argument again. 

Then I brought out a blue jean dress. She always said blue is her favorite color and always liked to wear something in blue. But this time, she said no and her favorite color is not blue anymore, but pink. 

I tried to figure out why she only wants this dress, so is it color? It turns out it's the style. It has a twirly edge at the bottom. She likes the dress twirls when she spins. Knowing that I showed her that the blue jean dress twirls too and tried to persuade her to try it on. But she refused to take off the pink dress and cried very hard. I almost lost it. I found I easily get agitated by her crying. Finally, she tried on the blue dress and refused to agree that the dress twirls even when I showed her a video of her spinning the dress. 

Well, I lost this battle and agreed on her wearing the same pink dress again. 
I then googled the solutions to this problem. I am not surprised that this problem comes out and even glad that she has her own mind now. Solutions include:
1. Make a rule that if her outfit is dirty, your daughter has to pick out something else.
2. tell her she can wear her favorite pants and shirt to school every day as long as she is willing to wash them every night. 
3.  tell her that you will wash her favorite outfit twice a week, so she can wear it every Monday and every Friday
