This crochet pattern is for a sleeveless round neck mens top. The design features a mesh pattern with a wide border around the hem.
The instructions include lots of detail to ensure complex shaping is made easy. The pattern includes details for making the five different sizes, small, medium, large, extra large, and 2XL, and is colour coded to help follow a particular size.
There is a lot of stretch in the finished item, so the sizing is only approximate.
I have listed this pattern as intermediate" because of shaping and being able to read a pattern with multiple sizes.
