Let's draft the pattern for this funny shirt - it is inspired by menswear but has very feminine details as the pleats to bust point, the waistband and the one shoulder neckline.
We suggest to sew it in cotton popeline, a striped version would accent some of the details and you could play with stripes direction - that would be cool! but you can also keep it plain and maybe accent collar and cuffs using a contrasting color.
To draft the pattern, start from a basic dress with darts and zero to very small ease at bust circ (2 to 4cm max).
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.
Copy back and front mirrored as the neckline is asymmetric.
