The men’s 3 measurement sloper, or alternatively, an adaptation of the Bunka-style adult woman’s sloper for an adult man. Since I could not find this online or anywhere, I decided try adapting the Bunka sloper for men. Like the original Bunka sloper, this uses only 3 measurements (taken in centimeters): bust (the girth of the chest), waist (smallest part of the waist), and center back (from the base of the neck to the smallest part of the waist). If you’re going to follow the instructions, I suggest enlarging the images in order to see the equations better alongside the captions that describe the steps. Hopefully, you find this helpful, and if you try this out, please let me know in the comments what your results are. This is an experiment I’m conducting so I really need your feedback.
Step 1: Draw all boxes as shown, and perform all calculations. Note that the dotted lines here represet that a line segment is equally divided in half.
Step 2: Building off of the original boxes, draw darts at their locations and add all curves. Note that the dart percentage corresponds to dart% *(body width - [(waist/2)+3] cm), where body width = (bust/2 + 6) cm.
If these instructions are unclear, don’t hesitate to message me or leave a comment on this post, I had to keep them fairly brief since this is Tumblr.
