Reference: New York Yankees Gray Nike Replica Jersey

Bodice: ESMOD men bodice block with dart, following with shirt enlargement. I simplified the instruction by removing waist shaping.
Sleeve: ESMOD men sleeve for fitted shirt.
Fabric: I have no idea whether the real fabric is woven or knit. I use ponte jersey.
Not shown in video: Topstitch. Graphics. I also edit the fabric texture to add the stripe on the sleeve band.
****** I never saw a baseball uniform in real life before. Baseball is not a thing in my country. Sorry if I got some detail wrong. ******
