We’re proud to offer custom sizing at no additional charge.

Given that we are operating primarily under a made to order production plan at the moment, we’re able to offer our clients custom sizing/alterations on any piece from our collection.

The only catch with a custom size is that we can’t offer returns or exchanges as we do with our stock sizes. This is non-negotiable.

If you’d like to request a custom size you can enter your instructions in the text box at checkout. We’ll follow up with an email if we have any questions.

In order to obtain your measurements we’ve attached a measurement tool for your reference. This diagram corresponds directly to our size chart listed on the website.

As noted, the sizing diagram directly corresponds to our size chart (i.e. chest, sleeve length, bottom). In order to create a custom piece, we ask that you provide your chest measurement (measure under your arm, all the way around the largest part of your chest), arm length (shoulder seam to wrist) and bottom (hips) or largest portion of your mid section. With these measurements we can create a custom size specific for your body type.

We also ask that you provide your measurements in centimetres to avoid deviation with conversions. Also keep in mind, that with a hand made garment that measurements may deviate +/- 1cm.

Please use a rope or sewing tape as opposed to a metal retractable constriction measuring tape.

If you’re using your actual body measurements as a reference for sizing, please add an additional 4cm to the chest and bottom when selecting your size in order to accommodate for the jacket lining as well as light layer of clothing. If you want to wear heavier layers, add a few additional cm beyond the standard 4cm increase.

Another simple way would be to measure a jacket from your closet; we could easily replicate the sizing. In this case please clarify that you have measured an actual garment so that our production team can account for that.


If you have any questions along the way, please don’t hesitate to reach out. You can email us at info@mastersupply.co and you’ll receive a response within 24hrs.
