From Sew DIY:
The vintage-inspired Summer Sweatsuit is equally suited to warm weather play or lounge activities. The sweatsuit consists of a racerback tank with a curved hem and mid-rise short shorts. The Summer tank top has a full coverage racerback style with a medium-scoop neck and curved hem. It's designed to be fitted at the bust and skim over the waist and hips in a swing style.
The Summer shorts feature an elastic waistband and a high cut curved leg opening. There are no side seams in the shorts, making them extra comfortable on sensitive skin. If short-shorts aren’t your thing, the pattern shows you how to lengthen the legs of the shorts.
These garments are quick-to-sew so that you can get back to summer activities in no time. This pattern has a close fit and requires knit fabric with stretch.
Model is 5’11” and is wearing a size D tank top and size E shorts.
