H1-KEY are back and turning heads with their music video for ‘Unbelievable,’ a hard-hitting electronic pop track that blends heavy synths with a fierce, sci-fi warrior concept. Moving from a locked concrete cell to a rainy airfield, a rooftop high above the city, and the deck of an aircraft carrier at sunset, the members trade the sweet school-uniform styling of ‘To. My First Love’ for black leather, buckles, and navy combat gear.
Fashion enthusiasts and fans are in for a treat as their outfits showcase a mix of cropped leather jackets, corset tops, utility vests, and chunky boots. If you’re looking to add a dash of tough, girl-crush edge to your wardrobe, here’s a breakdown of the standout looks featured in H1-KEY’s ‘Unbelievable’ music video!

Seoi’s Look
Seoi locks in on a rain-slicked airfield, aiming her weapon straight past the camera in one of the video’s early action shots.
Her navy leather corset top is cut with a pointed hem and outlined in silver piping, then paired with a belted navy mini skirt and a matching cropped jacket pushed up her arms. It’s the clearest preview of the blue-leather styling the group teased in their second set of concept photos.

Riina’s Look #1
With her platinum hair pulled into a high ponytail, Riina strides across the same runway with a rifle at her side.
She layers a super-cropped navy jacket with a keyhole cutout over a glossy blue leather bustier, then adds navy cargo shorts with strap details and lace-up combat boots. The contrast stitching on the jacket keeps the all-navy look sharp instead of flat.

Riina’s Look #2
High above the city on a glowing rooftop stage, Riina switches to a washed charcoal palette that matches the group’s black-and-gray dance outfits.
Her sleeveless funnel-neck top is crossed with black straps and worn with long arm warmers, black shorts, a thigh strap, and knee-high black boots. It’s a moody, futuristic take on utility dressing that’s easy to copy with a simple high-neck top and tall boots.

Hwiseo’s Look #1
Hwiseo makes a dramatic entrance, stepping out of a glowing cargo container with her bright red hair spilling over her shoulders.
She wears a washed black cropped leather jacket over a black corset top, finished with layered eyelet belts on black cargo pants. The rugged textures and metal hardware set the tone for the “female warrior” concept H1-KEY are bringing to this comeback.

Hwiseo’s Look #3
Out on an abandoned highway, Hwiseo stands guard with a rifle in one hand and what looks like a robot’s head in the other, one of the video’s most memorable shots.
She wears an oversized navy bomber jacket slipped off her shoulders over a dark mini skirt, then adds a thigh strap and chunky knee-high platform boots. The volume up top and the heavy boots below make for a bold, balanced silhouette.

Yel’s Look #1
Yel opens the video trapped in a concrete cell before crossing through a mirror into another world, and she brings the same outfit into a neon-purple prison corridor.
Her black leather crop top is strapped with buckles and eyelets, styled with fingerless leather gloves, a long black arm warmer, and low-slung black cargo pants. It’s the edgiest look in the video and a masterclass in mixing hardware with bare skin.

Yel’s Look #2
As the sun sets over the ocean, Yel dances on the deck of an aircraft carrier in the group’s navy finale look.
Her boxy, collared navy vest is covered in zips, eyelets, and metal rings, and she layers it over a blue leather bustier with sheer mesh arm warmers. If you love a utility vest, this is the look to save.
