If 2025 was about soft-girl aesthetics and cozy nostalgia, 2026 is shaping up to be… a little weirder. In the best possible way.
Trend forecasters are already pointing toward what’s being dubbed the “Extracelestial” aesthetic — a vibe that blends futuristic silhouettes, metallic textures, geometric shapes, and a touch of the uncanny. It’s not full-on space cosplay, but it’s definitely giving: “I might live on another planet, but I still have excellent taste.”
Which made us think: if fashion is looking to the stars, why not look back to one of the most gloriously strange, campy, and wonderfully bizarre depictions of space ever to grace television?
Yes, we’re talking about Lost in Space — which is why we’re leaning into Lost in Space fashion for 2026.
Between the ultra-structured mini dresses, unexpected color pairings, geometric cutouts, and aggressively dramatic performances (Dr. Smith still makes our skin crawl), the show feels oddly — and hilariously — relevant again. Instead of treating it as pure nostalgia, we decided to mine it for style inspiration and imagine how those iconic looks might translate into a modern, wearable, very-2026 wardrobe.
Here’s how we’re translating Lost in Space fashion into real life today.

🌌 Penny Robinson: Demure Lost in Space Fashion
Penny’s sleeveless A-line yoke mini dress with that single, crisp center inverted pleat is — frankly — almost impossible to find off the rack in 2026. Unless you want to hunt down a vintage ’60s sewing pattern (and maybe learn how to sew), this exact cut is frustratingly rare.
That said, Amazon actually came surprisingly close to the vibe — even if it lacks Penny’s signature front pleat and geometric bodice cutout. The version we found leans into that same bold, space-age geometry with contrasting color blocks that feel very 1960s groovy… and honestly? We’re kinda here for it.
If you can wear a size large and want to lean harder into Penny’s original color palette, the green/blue option is your best bet (though, fair warning, at the moment it’s available only in that one size). The red/pink version is less “celestial,” but it’s undeniably cool.
We’d save the pink turtleneck, tights, and go-go boots strictly for a costume party — but worn on its own with sleek heels and simple jewelry, this dress is a chic, head-turning statement in the good kind of way.
🚀 Mrs. Robinson: Refined Lost in Space Necklines
If Penny’s dress is hard to find, Mrs. Robinson’s neckline might be even trickier.
That structured stand (band) collar with a V placket and fabric-covered buttons she sports in color episodes? Shockingly rare. Finding one that doesn’t look overly retro — let alone one with matching fabric buttons — is no small feat.
But we did track down a beautiful silk & spandex blouse that captures the spirit of her look while feeling entirely modern and office-appropriate (yes, even if your “office” is technically a spaceship). The soft, light green shade also feels perfectly aligned with the Extracelestial trend — subtle, cool-toned, and just a little otherworldly. It’s a subtle reminder that Lost in Space fashion doesn’t have to be just camp — it can be genuinely elegant.
Our styling tip? Resist the urge to more fully channel Mrs. Robinson by layering a V-neck sweater over this piece. The collar is the star here. Instead, go with delicate jewelry and maybe even a sleek French twist to let that gorgeous neckline take center stage.
🛸 Judy Robinson: Cool Older Sister Energy
Where Penny is sweet and schoolgirlish, Judy is cool older-sister energy — confident, capable, and unflappable.
Her square-neck, jumper-style mini dress with two inverted pleats reads more “space babe” than “space child.” And while that cut is equally hard to find today, you can still capture the essence of her look.
We found a corduroy overall dress/romper on Amazon that hits the same architectural, structured feel — and yes, you can absolutely wear it with a turtleneck underneath without it feeling ironic. You’ll likely have to stick to more muted colors than Judy’s original purple/green/yellow combo, but the spirit is there. (And YOU’LL know you have that interdimensional swagger.)
✨ Spacesuit Chic (If You’re Feeling Bold)
If you want to nod more directly to the show’s actual spacesuit aesthetic — and lean into Lost in Space fashion more literally — two pieces feel very on-trend for 2026: a metallic silver top from Janet Howard New York and a pair of sleek, plated silver jeans (currently on final sale at Joe’s Jeans).
We wouldn’t recommend wearing them together unless you’re intentionally going for a full “runway-from-another-planet” moment — Danger, Will Robinson!
Styled separately, though — with gray, black, or even crisp white — either piece reads very “extracelestial” in a modern, wearable way.
And if, in your head, you’re channeling your best cool-girl Judy Robinson energy — all while pretending to be held captive by a giant carrot alien who’s screaming “MOIST-YAH!” (not that that’s our favorite fever-dream-level episode or anything) — well, that’s between you and your imagination.
Besides, if Lost in Space taught us anything, it’s that even in a crisply tailored “uniform,” things can still get gloriously unhinged.
("Gloriously Unhinged": Exhibit A)
🌠 Final Thoughts
Whether you’re drawn to Penny’s geometric sweetness, Mrs. Robinson’s refined elegance, or Judy’s cosmic babeness, Lost in Space offers a surprisingly rich wardrobe for reimagining in 2026.
Extracelestial style doesn’t have to mean dressing like you just landed from Mars — it can simply mean embracing bold shapes, unexpected textures, and a little bit of delightful weirdness.
And if you do it while channeling a vintage sci-fi classic that somehow manages to be both visionary and completely bananas? Even better.
