Outfit change at reception

Hi WW community,

My question about outfit change is not really whether to change but when to change...

i have bought an Elizabeth Fillmore wedding gown that i absolutley love. It’s in organza silk wi cascading flowers down the side and in the back with a beautiful train. My mom has also gotten me a silk red ankle-length traditional Chinese dress for the reception. Sidebar- it’s quite common for brides to do multiple dress changes at weddigs in China.

I love my gown and would really like to wear it for the first dance, and also want to honor and appreciate my mom’s gift by wearing the red dress.

Here are the questions:

Can I do the first dance during cocktail hour? And then change into the red dress when announced at the reception?

Can I change back to the gown again at a later point? Believe it or not the wedding gown is actually more comfortable. I can raise my arms all the way up and the side slit isn’s all the way up to almost my butt like the red dress :’)

Would love some perspective from everyone!
