THE BUSINESS-T, A refined T-shirt for the modern professional, perfect under a jacket
A new essential T-shirt designed for today’s businessman, offering a clean, polished look whether worn on its own or as an inner layer under a jacket. Made from our signature PREMIUM CIRCULAR fabric, also used in our stretch shirts, this business-ready T-shirt combines quality and functionality, setting it apart from ordinary casual tees.
Cotton 47%, Polyester/Polyethylene 53%
Made in Japan
Material
The outer surface features 80-count SUPIMA cotton, known for its smooth texture and elegant sheen, while the inner side uses a composite fiber (polyester + polyethylene) for comfort and performance.
Special fibers prevent light from passing through, achieving a “white yet non-see-through” effect.
Polyurethane yarn is knitted into the collar, providing stretch and allowing it to flex comfortably with neck movement.
Functionality
Maintains a smooth, dry feel even when sweating—ideal for business settings.
Excellent recovery (kickback), helping the fabric retain its shape and resist deformation.
Offers UV protection to shield your skin from strong summer sunlight.
Opaque enough to be worn on its own with confidence.
Design
The neckline features a slightly wider rib. This adds subtle volume and structure around the neck, giving a simple T-shirt a refined accent.
The collar is designed slightly higher to prevent direct contact between your skin and the jacket, helping reduce wear on the jacket.
Ideal for business casual outfits.

A fantastic shirt with a timeless Ivy style. The seersucker fabric is lightweight, breathable, and perfect for warm weather, while the construction and overall quality are excellent.
For sizing, I'm typically between a European 39/40. I chose a 16½ for a more comfortable, relaxed fit, and it was exactly what I was looking for. If you prefer a roomier fit rather than a tailored one, sizing up worked well for me.
Versatile formal trousers with excellent fabric, tailoring, and overall construction. I'm very happy with the quality and fit.
For sizing reference, I normally wear a 34-inch waist. Based on my previous experience with Kamakura, I usually size up by one, so I ordered a size 50—and it fits perfectly.
If you're between sizes , consider sizing up. I'll definitely be buying more colours in this style.
As an older fella who’s enjoyed (or been underwhelmed by) OCBDs from shirtmakers over the years (e.g., Troy Guild, Brooks Brothers, Sero, Mercer & Sons, Jake’s (London), Drake’s, O’Connell’s, Individualized), this Kamakura AMETORA shirt is a valentine to what a classic OCBD is supposed to be; it definitely checks all the boxes: full cut, unfused placket/ cuffs/ collar, the correct placket width, medium weight cloth, and a collar-roll as god intended (and few makers get right). Great sizing, too: i typically get a 15.5 X 33 shirt and this 15.5” turned out to be perfect in the sleeves for me. More color options, please.
I was a bit reluctant to make this purchase because I couldn't decide whether the Medium or Large would be the best fit. For items like this, I would normally buy a Medium. For reference, I'm 6'2" and 165 lbs. After going back and forth - and reading that this garment is intended as an overshirt - I decided on the Large size. Lucky for me, the fit is perfect. It's not too big. It drapes beautifully, and the design, with its simplicity and clean lines, is exactly what I was looking for. I'm hard to please when it comes to clothing. Purchasing online is even more daunting. Ordering internationally without a return policy felt like a real bet. However, I made the bet, and I'm very happy that I did. I've had it for less than a week and have received multiple compliments from multiple strangers, which is unusual - more of a testament to its beautiful simplicity.
