Based on the French coverall. the silhouette has been adjusted to have a slightly looser body and sleeve width. The sickle collar shape has been narrowed around the outside of the collar to make it closer to a shirt collar. the cuffs have been changed to barrel sleeves. the shoulders have been slanted to make a natural shoulder. and the back body has been made into one piece without the center seam on the back. making it easier to wear.
