Collar/Neck alteration with Shoulder alteration for sleeveless
Making a sleeveless, button-front top with rolled collar (no collar stand). Description: Top button is 9-1/2″ down from neck point (shoulder seam) on original garment pattern. 1st Alteration: the shoulder seam needed be pinched out 1/2″ from shoulder point to neck edge (helps with gaposis in armscye which was too large, and took out diagonal excess fabric in bodice front, horizontal in back, also made bust darts line up at correct angle/height). However, this created front and back pattern pieces that do not line up well. Where should the seam & allowances be added/subtracted from to smooth the alteration for sewing?
2nd Alteration: To the rolled collar. Alteration #1 shortens the collar by 1″ on left, 1″ on right (1/2″ front & back, left and right). Can this be done for it to lay properly, while turning the lapel of front bodice as is meant to?
Or other suggestions to make this narrow neck, shoulder, sleeveless armscye look great?
