I don't know about "gender fluidity," but Gigi Hadid has much more successfully blurred the lines between sleep and waking, trotting out several pairs of pajamas in the daytime. But there's a difference between clothes made for snoozing in and those just designed to look that way. Test yourself ahead.
Pajamas or chic Palm Beach granny?
Morgan Lane, $558

Real PJs or just a great example of trompe l'oeil?
One hundred percent, USDA-certified intended to be worn IRL. A similar look from the same designer Christian Dada shown here.
Did she tumble out of bed into a Met Gala after-party? (Would not put it past Rihanna, honestly.) Or did she get dressed With Purpose?
Purpose (tour). This is Prada Spring 2017 and in my top 10 favorite collections ever, probably.
C'mon—you can figure this one out.
Prada again, dreams again.
When you're out past your bedtime so you dress to turn in immediately once you're home. Or not?
Yes—these are Prada, but they're Prada *pajamas.* Which also makes them $2,000.

Designed for a duvet day? Or a duvet day the Taylor Swift way, where you're literally wrapped in a duvet but in the car on your way to do important things?
Technically, both, but collectively, these are classified as a sweatsuit—a cashmere sweatsuit.
Olivia van Halle, $1,235
BUY IT: net-a-porter.com.
Nightie? Or, uh, day-ie?
Day-ie. (The leather should've given it away.)
BUY IT: Jitrois, $2,288; jitrois.com.
PJs or real clothes? (I'm getting tired.)
Proper PJs, very subtly printed.
Derek Rose, $225
BUY IT: derek-rose.com.
Rihanna out at 3 a.m., a fact that doesn't help you guess at all.
But she's still in her party clothes, the trooper she is. These co-ords are from Fleamadonna, a genius name if we ever heard one.
Nightgown? Or a longish dress one wears in the evening?
The Row, $3,990
BUY IT: barneys.com.
Who even knows with Kim (but actually her stylist, AKA Kanye)?
They're real. But sold out, unfortunately for Ann Demeulemeester fans.
We know she's got a thing for onesies, but is this one built for lounging?
Nay—raging with your superhero pals. (That's what the print is.)
If anybody has tailored pajamas, it would be Rashida Jones. Or Thom Browne.
But she doesn't! The shirt and trousers are Erdem—amazing what a sheer cape can do, eh?
This was a premiere for her movie Battleship, which is criminally underrated and actually a cinematic gem, if only for the part where she goes "Mahalo" before blowing the aliens to kingdom come. But even with that context, one can never be sure.
It's Emilio Pucci, and it's mega.
Awww! This was in 2009, so Joan Rivers (RIP) probably slammed her for this, but we're into it.
And so were Stefano Gabbana and Domenico Dolce—because they made it.
