From Trend Patterns:
Shirting and especially patchwork or mismatched shirting is a popular street and catwalk trend for SS18. This is a combo pattern so there are shirt and shirt dress variations, with wide sleeves for a sharpe but casual silhouette. The dress has a drawstring at the waist giving a cinched in shape and the shirt has a drawstring on the hem making it casual and cool.
Make yours with pinstripe shirting and cut panels with horizontal and vertical lines to get the effect too.
Buttonhole setting on sewing machine needed. Follow instructions for placket construction.
