The neck is a touch short but if you futz the shirt it can help. With tucked shirts I always strip the figure down and tape the shirt to the thighs and butt. I also did a tuck on the back so that the shirt fit the body a little tighter. Your really have the have the shirt pulled down to the shoulders for it to work right. Its not like an HT where there is a huge gap between the shoulders and neck. Other then the technical problems that can be had with the Enterbay body, I for one really like them for their proportions. The suit fits the body perfectly.
Thanks for the wisdom bro! Got some work to do!
