Trims & notes
• 18L buttons x9 (7 front, 2 cuff) + 2 spare
• Lightweight fusible (collar and placket only)
• Woven main label (back neck)
• Care/content label
• This is the easiest garment in the library to get right on sample one: no lining, no padding, no fusing in the body, no zip. If you are making your first ever production run, start here.
• Fuse the collar and placket only. Every first-timer who fuses the fronts ends up with something that feels like a uniform shirt.
• Straight hem, not a shirttail. It is a two-centimetre decision that changes whether the piece reads as a shirt or a jacket.
• Back print area: 30 x 26 cm, starting 12 cm below the yoke seam.
