Fashion Disaster
Asking about an outfit
SceneTina is at the mirror in her room before going out.
WORDS & CONTEXT
Words & context
“the wrong pants”
In American English, pants means trousers, rather than underwear as the borrowed Japanese word often does. In British English, pants can mean underwear, so trousers is used for the outer garment. Tina has chosen the wrong trousers for her outfit.
“completely out of place”
Out of place means not fitting the setting or surrounding things. Tina feels that her shoes do not match the rest of her outfit.
“Most people aren't gonna look that closely.”
Most people means nearly everyone, and look closely means to look carefully at details. Here that closely means "in that much detail," referring to the outfit details Tina is worrying about. Gonna is a casual pronunciation of going to (see A2-04). Frank does not deny the size problem he noticed; he comforts her by saying the people she meets will not look that carefully.
“Easy for you to say!”
Easy for you to say! shortens That's easy for you to say. It expresses mild frustration that someone can give advice easily because they do not face the same concern.
“I literally wear the same thing every day, Tina.”
Here literally is an intensifier: "truly, exactly." In this scene the same thing means the same outfit. Frank wears his usual clothes every day, including the brown jacket. The punchline is that the person Tina envies for always looking perfect never chooses a new outfit at all.
