Steve likes them loose and long.
(colette patterns here) has all that. I had a better time understanding all the finishing details this time round (3rd) and have finally figured out the button hole foot.
Steve redrafted the collar details so that the collar doesn't lie too openly and look like a deflated balloon. However, I'm not keen on how the collar joins into the shirt front. Neither am I keen on the button hole placements. I didn't make any adjustments, I followed the markings and they just look wrong to me.
