From OurLadyOfLeasure:
The Gimlet Boilersuit is high-fashion utility wear! Boilersuits are so in right now, and with the Gimlet,you can put your own spin on the catwalk style.
This boilersuit features hip pockets, faux breast pockets, and a loose fit which is cinched with the matching belt. We’ve simplified the design with a ‘convertible’ collar and rolled sleeve hems.
Skill Level: Intermediate
These instructions are aimed at intermediate sewers.
The garment construction is straight-forward, but there is some top-stitching required, which may not suit beginners.
