Lily: "Sev, oh Sev, just this once!"
Severus: "Lily, I am not a girl. I am not wearing makeup. I am not wearing a dress, and for Merlin's sake, I am not pretending to be a girl."
Lily looked at him with her doe-like eyes, and sadly, Severus was not immune to that. "Please?"
What happened after that was hours of some sort of makeover. Lily didn’t have a problem with his hair because he already kept it long. She washed it, applied some potions, and dressed him in an oversized black turtleneck sweater paired with a pinstriped skirt. She added leather boots, a jacket, and some makeup.
Lily: "Let’s go to Hogsmeade. I promise no one will recognize you."
Sev: "I am not doing that."
Sev: "Fine… just for the sake of seeing if anyone recognizes me."
The Marauders were having fun walking around Hogsmeade when James noticed a girl with red hair.
James: "Padfoot, Moony, Wormtail look at that lady with Evans."
Sirius: "She looks kinda cool. Similar to my aesthetic. What are the chances she’ll say yes to a date?"
Remus: "Doesn’t seem like a good idea."
Sirius (flirty tone): "So, Evans, who's the pretty lady with you?"
For a moment, the girl almost sneered. It looked very similar to someone, though he couldn't remember.
Lily: "A friend from another city. Severina."
Severus glared at her, but Lily just looked bemused.
James: "Witch? Obviously, what would she have been doing in Hogsmeade otherwise?"
Sirius: "So, Severina, would you go on a date with me?"
Severus: "No. Let's go, Lily."
And Lily held Severus's hand, giggling and walking away.
Remus: "She looked familiar."
