Maru Sankaku Peke by SDA "Kimono" S/S Open Collar Shirt (6 Different Designs)

Size Guide
An EAST meets WEST combo!

OAX have connected western culture with Japanese culture yet again! This open-collar 'aloha' style shirt is made with B.N.D.S (Brand New Deadstock) vintage Kimono fabrics sourced from local Japanese farming families.

For those who don't know, OAX focus on remaking garments with rare vintage fabrics. These shirts are made of 100% silk-printed Kimono garments from Japan. Each batch is sourced from leftover fabric saved by the local family and sold in extremely limited quantities so there is only enough to make one pattern in each size. Due to the limited amount of each pattern, the luxury silk fabric can be sold at a similar price to cotton!

For a casual look, the collar features an open design with a hidden button if you prefer to fasten it up completely. To add some tasteful contrast, OAX has used polished shell buttons that have a beautiful natural sheen.

For those who have a taste for traditional Japanese culture with a western fit, you'll enjoy this one, no doubt!

How We Measure

Pants and Shorts


With the major buttoned up (i.e. the top button) open the jeans and lay them flat, like shown. Measure from the front where the major button closes to the back belt loop. Double this measurement to find the waist measurement.

The way we measure the waist is different from the 'Side to Side' technique. If you are used to the 'side to side' technique you can roughly roughly downsize by 1 inch.

For example, 'side to side' measurement for The Flat Head 3002 waist is 28inch and using our method measures at 29.25inch.

Front Rise:

With the jeans lying flat measure from the crotch bar tack to the top of the waistband. 

Back Rise:

Spread out the crotch so the bar tack is visible, then measure from the crotch to the top of the waistband.


One inch down from the crotch, measure flat across to the other side.


Flatten the leg and measure along the inseam from the crotch to the leg hem. 

Leg Openning:

Measure straight across the hem from side to side.





Lay flat then measure from the shoulder's edge to the other shoulder's edge.


Lay shirt flat and measure from pit to pit.

Sleeve length:

With the sleeve flat measure from the shoulder to the cuff.

Arm hole openning:

Measure from the shoulder down to the pitt.

Vertical length:

With the shirt facing down, Measure from below the collar to the bottom hem.
