【INTÉRIM】9 types of summer cut-and-sew tops.
Suvin cotton versus merino wool: the ultimate choice.
Arzac Kamakura has selected INTÉRIM as the brand that best embodies the balance of "texture and comfort" for summer tops. The 2026SS summer cut-and-sew collection features two materials and two styles: Suvin cotton and extra-fine merino wool. We will introduce all nine items in the lineup.
What is INTÉRIM?
Founded in Japan in 2019, this unisex brand takes its name from the word "INTÉRIM," meaning "temporary, provisional, or temporary," and continues to offer only timeless items amidst the rapidly changing fashion scene.
With the motto "Using the finest materials and supplies from around the world, and bringing them to life with Japanese craftsmen," they actively use rare materials such as deadstock fabrics from LVMH and Hermès, Suvin cotton, and extra-fine merino wool. They are committed to sewing at domestic knitwear factories and dress shirt factories, and continue to create garments that maximize the luxuriousness of the materials.
ARZACH KAMAKURA is an authorized INTÉRIM retailer in Kanagawa Prefecture, stocking the latest collections regardless of the season.
Learn about two materials – Suvin cotton and extra-fine merino wool
This season's summer cut-and-sew tops are available in two different materials. Understanding the characteristics of each is the key to choosing the perfect piece.
HIGH GAUGE SUVIN JERSEY
Made with 100% Suvin cotton, one of the world's rarest extra-long staple cottons. Grown in South India as a hybrid of Supima and Ceylon cotton, the fibers are extremely fine and long, possessing a silky luster and smoothness.
Interim uses a high-gauge knitted jersey fabric. It has a substantial feel without clinging to the body, promising the ultimate in cleanliness during the sweaty summer months.
EXTRA FINE MERINO WOOL JERSEY
This original wool jersey fabric uses 48-count single yarn made from extra-fine merino wool. The raw fabric has a strong sheen, and further special processing during finishing achieves an exquisite luster, a smooth surface, and a beautiful drape.
Merino wool quickly absorbs and wicks away sweat, keeping you feeling dry and comfortable. It also boasts odor-resistant properties and is wrinkle-resistant, making it the perfect material for summer.
Getting to Know Type 2 – HENRY OVER and S/S TEE
| type | neck | silhouette | For people like this |
|---|---|---|---|
| HENRY OVER | Henley neck (placket + genuine buffalo horn buttons) | A relaxed, oversized silhouette. Generous shoulder and body width. | For those who want to achieve a relaxed and sophisticated look. For those who want a stylish outfit that looks great on its own. |
| S/S TEE | Crew neck (fine rib) | A clean and simple short-sleeved T-shirt. A minimalist design free of unnecessary embellishments. | For those who prioritize versatility. For those who want to wear it as an inner layer or on its own. |
NOTE — About the size
All Interim cut-and-sew tops are available in three sizes: 3, 4, and 5 (some are only available in 4 and 5). Size 3 is roughly equivalent to a typical Japanese S size, size 4 to M, and size 5 to L. Because HENRY OVER has a relaxed silhouette, many customers choose one size smaller than their usual size. We recommend trying them on in-store.
Suvin Cotton × HENRY OVER
This oversized Henley neck sweater is inspired by the garments of a long-established British knitter, a symbol of fine-gauge knitwear. The generous width of the body and shoulders prevents it from clinging too tightly to the body's lines. Yet, the supple drape of the Suvin yarn creates a refined look. It can be worn alone or as an inner layer under a shirt or jacket.

STAFF'S NOTE — From the ARZACH staff
"There are differences between the two that you only truly understand once you try them on. Suvin cotton offers the comforting feel of a T-shirt combined with overwhelming quality. Merino wool has a feel that's on another level from the moment you first touch it. You won't regret choosing either, but if you're undecided, try both on at the store."
