How to choose your size

Body Measurements:
Measure yourself and compare your actual measurements with the body measurement table in the picture section. If your measurements fall between two sizes, choose the larger size.

How To Take Body Measurements

Garment Measurements:
Lay a similar garment flat on a table and measure from side to side to get half of the total garment width. Note that woven garments are much wider than the body, so their measurements will not be the same as your body measurements.

Understanding Garment Ease

How to download the sewing pattern

After your order, the file is available for instant download via the link in your confirmation email. Ensure you have entered the correct email address. If you don’t receive the email, send a message to info@mascultory.com with your name and your correct email address.

Save the downloaded file to your hard drive and unzip it with a right click on PC or a double click on mac. Inside the sub-folders, you will find the instructions and the pattern PDFs for home printers and for A0 format.

Smartphones struggle to display all PDFs within the folder, so it’s best to use a PC.

If you're downloading on a different device than the one you bought on, make sure that device isn't using a VPN.

Every pattern contains these files:
-Instructions.pdf
-HomePrinter.pdf
-A0.pdf

Each size has a separate PDF.

How to print

Each pattern is printable on a home printer. Set the printer to 100% scale. Never use 'fit,' 'shrink,' or anything other than 100%.

Each page has a frame measuring 10½ x 7¾ inches or 26.7 x 19.7 cm. Ensure each page has this frame printed with exactly these dimensions. If the black border line is missing on any of the four edges, correct the printer settings. Do not proceed with sewing until the frames are correct.

Printed Page Taping

If you don’t like taping pages, you will find an additional A0 PDF for copy shops or projectors. Do not confuse the A0 PDF with the home printer PDF. The file names indicate whether they are for home printers or for A0 copy shops, and the page dimensions are written in the upper left corner of the page.

Product details

So simple to make with very easy to follow instructions. Came up very true to size and the front pouch was perfect.

This is a great pattern and the video instructions are great as well. Everything was explained well and thought out. Lots of sizes to choose from. Although these do fit well, sizes seem to run a little small and the briefs are a too little low (on hip & pubic area) had to raise the pattern height on the waist/hips. Also it would be nice to have the same sizing options, as well as have an option for those with larger male parts down there, as the front area which holds the goods is a little too snug, had to extend that as well.

The pattern printed out correctly and assembles without any of the lines being off. I'm glad I bought the multi size pattern because the first one I tried was a bit too large. Each size comes in a separate file which is very useful if you've tried to assemble a pdf pattern with multiple sizes on one page! Another very useful bonus is that Joost includes pattern markings for dividing the elastic.

Had a really fun time with this pattern. This is the second project I've done by pattern (first digital), and it was a breeze. Obviously, it's pretty basic, but the video directions were helpful, and the finished product is soooo comfortable, and feels very sexy. I can't wait to play around with different prints and replace all of my tattered, old undies. The only change I would make (which I did), would be to add a fly. All I did was print out the pouch pattern piece twice, and on one of them, I cut an arc from the leg hole notch to the intersection of the seam allowances in the corner where the pouch meets the back and waistband. I then put FOE on that edge, in addition to all the others, and proceeded as usual. I feel like a variant with a fly would have been a simple and worthwhile addition to an already excellent pattern.
