Some people write bylines.

Megan O'Sullivan
is Byline.

She’s the kind of cultural force that makes you rethink not only what you want, but why you want what you want. Before you even finish reading one of her pieces, you’ve already mentally bookmarked a designer, refreshed your cart, and perhaps even questioned a belief or two about culture. So it's only natural that she is the brains behind Byline, a print mag and cultural north star for the iykyk crowd.

When she’s not writing for Byline (!!!), The New York Times, i-D, Vogue, GQ, or T Magazine, or her own Substack First Draft, she’s probably doing something you wouldn’t expect (see: purchases). On brand. Her writing is breezy but built to last, stylish but lived-in. Like a well-worn Gap tee from your childhood drawer, or, say, a Brooke Callahan capri with just the right slouch ;)

(Side note: she’s the Content Director at Gap so yes, she’s THAT good at breathing new life into nostalgia.)

First Draft
Nostalgia is the only thing I like about clothes
Last week, I received a text from my friend and editor Sarah Spellings about a t-shirt she bought: a brown, black and white striped, slightly oversized knit shirt from TWP. Sarah described it as “crush core” — she would know, as she was the editor for the…

For today’s Selleb Spotlight, Megan opens up her summer cart, equal parts utility and pure unexpected delight. From Brooke Callahan’s now-iconic tie pants to an $18 self-excavation kit, these purchases tell a bigger story about living in a hot city, enjoying the presence of friends, and dressing with a plot.

Without further ado,

Megan’s Receipts


  1. Brooke Callahan Tie Pants (resale version here): “The Brooke Callahan craze is not new by any means (in fact, the designer’s rise is reported on thoroughly), but it’s definitely picking up speed and I’m very much on board. I see Callahan’s signature side-tie drawstring pants and capris everywhere now that I’m privy. My first purchase from the LA-based designer was this white skirt, which quickly became one of my most-worn staples. The 100% cotton poplin is equally soft and crisp. The drawstring is perfectly thin. The sizing is true. I then purchased the Tie Pants in Chocolate, which felt like a cute option for morning coffee run-esque outings. Those were such a success that I decided to go for the Tie Pants in Red, and it was all over. I was converted. The color was an impulse decision—I couldn’t decide between the Turquoise or the Pink or the Red, even though my senses told me to go with the Black. Alas, here I am, the girl in the red pants.”
