Kaley Cuoco is the mom of a toddler, so what she wears to bed is different now than before she had Matilda.
And thanks to The Gilded Age, she has been inspired to buy a nightgown that would be fitting of the series. However, it is not fitting to her body!
By the looks of it, she doesn’t care! She is comfortable living the 1880s lifestyle. And she looks great doing so.
