From Closet Case Patterns:
The Blanca Flight Suit is a semi-fitted, highly customizable boiler suit pattern inspired by vintage workwear. With multiple sleeve and leg options, it can be made in a variety of fabrics and can easily be styled up or down.
Blanca features a center front zipper, patch pockets that double as belt loops, an optional tie belt or buckled belt, a traditional shirt collar and a unique pleated back design. Customize your flight suit by adding a long sleeve, tapered sleeve with snap button, or short sleeve. The leg is cut straight, with the option to crop it or taper at the hem with a leg tab. In addition, choose between a classic breast patch pocket or zippered pocket for added detail.
