From Sew Love Patterns:
The Springe Jumpsuit Sleeve Extension is the perfect add-on to the Springe Jumpsuit, that gives two new sleeves options so that you can wear the jumpsuit all year round! It has two different sleeve options. Version A is a full length set-in bell sleeve, that gathers into a buttoned cuff. Version B is the same set-in bell sleeve, that gathers into an elastic cuff at bracelet length.
Please note: You will need the original Springe Jumpsuit pattern to complete the extension.
Recommended fabrics: The jumpsuit works well with medium weight woven fabrics that have a drapey feel such as viscose, cupro, tencel, crepe and rayon.
