How to Style the Monica Geller Halloween Costume

The striped pants are the first thing people place, and they need to be genuinely high-waisted and fitted, a loose or low-rise pair reads as a completely different decade. Keep the crop top plain and simple, it’s meant to be a supporting piece rather than the focal point. At a party, if the pants get swapped for something more generic, the whole look drops back to “person in a black top” instead of Monica specifically.

Monica needs things done a specific way and gets visibly frustrated when they aren’t, which is usually the joke rather than a flaw played straight. She’s also the one who remembers every tradition and every rule of every game the friend group has ever invented, and she will absolutely bring that up unprompted.

High-waisted striped pants can run tight around the middle

If you’re planning to eat at the party, size up slightly rather than going for the exact fitted look. Comfort matters more than an extra half inch of accuracy.

A crossbody bag frees you up more than a handbag would

Since this look doesn’t come with any props to hold, a crossbody bag keeps your hands free for the rest of the night, which is more practical than a clutch or top-handle bag.
