Introduction: Mens Latex Y-front Brief

About: Marketing manager for MJTrends.com. We sell fabric (stretch faux leather, latex sheeting, vinyl, etc) and sewing notions (rotary cutters, scissors, fabric adhesive, etc). I love to design and try out new fas…

The mens latex y-front brief is typically worn as underwear and made from latex sheeting or 4-way stretch vinyl. It has a close fit the same way that traditional underwear or swimwear would fit.

Step 1: Gather Your Materials

Step 2: Cut Out Pattern Pieces

Place your pattern on top of your latex sheeting, and cut out the various pattern pieces using a rotary cutter on top of a cutting mat.

** When you cut out the trim pieces, add an extra 1/2 inch to the ends - if it's too long you can always cut away the excess, but if it's too short, you'll have to cut a new piece. **

Step 3: Glue Front Trim to Front Section

  1. Place the front section on your working surface and then layout your front trim pieces on top of it to ensure that everything comes together properly.
  2. Mark the location of the trim pieces on the front section.
  3. Brush on glue to the front section where the trim will go. Make sure that the glue is slightly wider than the trim.
  4. Starting at one end, adhere the trim to the glue. Working slowly down, and making micro-adjustments as you go.
    1. Try not to stretch the trim as you adhere it to the rear section.
  5. Press the trim to the front section using your seam roller.
    1. Use as much pressure as you can.
    2. Roll at a 45 degree angle to the trim.

Step 4: Glue Trim to Rear Section

  1. Brush on glue to the rear section where the trim will be placed. Ensure that the glue is slightly wider than the trim.
  2. Adhere the trim to the rear, working from one end and progressing slowly - making micro-adjustments as necessary.
    1. Try not to stretch the trim as you glue it.
  3. Press the trim to the rear section using your seam roller.
    1. Use as much pressure as you can.
    2. Roll at a 45 degree angle to the trim.

Step 5: Glue Front to Rear at Side Seams

  1. Put glue on the left side front and left side rear. Allow the glue to get tacky (wait a minute or two).
    1. Use a 1/4 inch seam width.
  2. Place the rear directly on top of the front, and work your way down the seam, adhering the front to the rear.
  3. If the front and rear do not match perfectly, either start over and try again (if more than 1/2 inch off), or carefully trim away the excess using your rotary cutter.
  4. Press the seam with your seam roller.
    1. Use as much pressure as you can.
    2. Roll at a 45 degree angle to the seam.

Step 6: Glue the Crotch Seam

  1. Glue the front to the rear at the crotch.
  2. Ensure that front and rear line up perfectly. You can stretch the material slightly if necessary as you are gluing it.
  3. Press the seam together using your seam roller.

Step 7: Glue Waistband (optional)

  1. Apply glue slightly wider than the width of your waistband, to 1/3 the length of the waist.
    • Start at the rear, overlapping the middle of the rear by 1/4 inch.
  2. Work your way across 1/3 of the waistband. When you get to the end of the glue, apply adhesive to another 1/3 of the waistband. Work your way slowly down that section, and then repeat 1 more time.
  3. Overlap the waistband by 1/4 inch over the waistband at the middle rear.
  4. Press the waistband to the brief using your seam roller.
    1. Use as much pressure as you can.
    2. Roll at a 45 degree angle to the waistband.

Step 8: Wait 24 Hours, Then Celebrate!

  1. Give your seams 24 hours to cure before putting any stress on them.
  2. Celebrate - you just made a pair of custom latex briefs!
