Style analysis: pinafore dress featuring a waist cut, princess lines ending at armholes on bodice and flared skirt with pleats. Dress has a fake buttoning in center front and an invisible zipper as closure.
You can sew it in any woolen fabric for a winter version (we recommend lining for it not to stick to tights), or in denim, corduroy, canvas for something to be used also with warmer weather. If you choose a plaid as the one in the image, pay attention to matching lines!
To draft the pattern start by tracing a copy of your basic dress with darts and 8 to 10cm wearing ease at bust circumference. You can learn our method for drafting perfectly made to measure basic blocks (contoured ones, and the ones with wearing ease) and for fitting them in our basic blocks course/module 1.
