"Sweatpants, hair tied, chillin' with no makeup on" is how you've seen your girl every day since you decided to make it exclusive. She already knows you think she's beautiful and aren't going anywhere, so you see her at her "realest."
Mention that your homie is coming through, though? She's going into the back of her closet looking for a dress, and spend an hour straightening her hair and doing her makeup. That's how she first caught your attention, right?
