LIFiLL / Side Slit Long Sleeve T-shirt
This long sleeve T-shirt is a more elegant update of LIFiLL's signature model "COTTONY(R) SWEAT LONGSLEEVE TEE".
"COTTONY(R) TENJIKU" is made of high-quality Supima cotton with softness and a silky sheen. It has a soft and supple touch that is gentle to the skin.
In addition, the silhouette is delicately stitched to provide a relaxed fit and comfort. The side slit subtly accentuates the design, making it a piece that can be used in a wide range of situations, both on and off the job.










LIFiLL
Created by Stylem Takisada-Osaka, a textile house with over 150 years of history, LIFiLL is a cut-and-sew brand built on deep material expertise. The name combines LIFE + FILL, expressing the brand’s philosophy: clothing that quietly enriches everyday living. Each piece is designed to harmonize with the wearer, offering a refined presence through simplicity.



The signature “COTTONY” fabric
This piece uses Supima cotton, considered among the highest grades of cotton. Only extra-long-staple fibers of 35mm or more—approximately 1.5 times longer than average cotton—are selected for its production.

The long, silky fibers create a remarkably smooth touch and a gentle, lustrous sheen reminiscent of silk. The tightly knit jersey produces a fabric with both soft drape and a subtle structure that enhances its refined appearance.

Elevated through thoughtful detailing
The neckline is a clean, modern crew neck with a balanced width that adds a composed look.

Fine stitching at the sleeves and hem, paired with subtle side slits, lends structure and sophistication. These quiet accents refine the silhouette and bring elegance to even the simplest styling.

Relaxed silhouette with modern ease
The gently loose silhouette offers both comfort and poise, while the drop-shoulder design softens the outline around the shoulders for an effortless fit.
It maintains a clean line without appearing oversized, making it versatile for both casual and refined looks—a natural complement to an adult wardrobe.
