Nebula and Thor
It took Thor a moment to place the redhead. He knew he had to know her otherwise she wouldn't be at the wedding, but this was not a face he was used to.
The dress was mesmerizing though and that was what caught his attention.
"Your dress reminds me of something my mother would have worn at a gala," he said fondly. "It looks both parts comfortable and intimidating. I commend you for your excellent wardrobe choice."
