Zink Layered LS

It can also be obtained through leveling up the Dizzle Season 2023 Catalog to level 66 as part of the Zink Layered LS Outfit.

Appearance
The Zink Layered LS consists of a long-sleeved, dark gray T-shirt and the short-sleeved white T-shirt worn over it. The white shirt has a large Zink logo on the front in black, white, and magenta, and a tiny, olive green tag at the bottom. A small version of the logo is printed on the shirt's back. Also at the bottom, the hem of the dark gray shirt can be seen poking out.

Trivia

 * The Zink Layered LS is the cheapest purchasable gear with Damage Up (in Splatoon) and Respawn Punisher (in Splatoon 2).
 * Players of the Splatoon Global Testfire who pre-ordered Splatoon were temporarily given a clothing similar to the Zink Layered LS and the White Tee with a large ink-colored squid sticker on the front as part of a then-exclusive set of gear. Since the Global Testfire did not create save files, it did not carry over into the full game.
 * Unlike the Studio Headphones and Red Hi-Horses, however, it did not become obtainable in the full game proper.
 * Inkling Boy's default variant wears the Zink Layered LS in Mario Kart 8 Deluxe.
 * The Zink Layered LS exists in real life, sold by KOG.
