Women’s 15th century Smock or Shift
This is your underwear, it is always made of bleached white linen. It should have long sleeves, under-arm gussets, a scoop neck and be between lower calf and ankle in length. The sleeves need to fit under the fitted sleeves of the gowns worn over it. The scoop neck should be low enough to not stick out much past the necklines of the gowns worn over it (a peek of your smock in the neckline of your gown is fine but preferably it should not stick out at all).
A possibility to consider while making your shift is to leave the neckline cut deliberately too high and left unfinished until after your gown is completed. Then you may mark your neckline exactly while wearing the gown over it. Many of our group prefer when the shift/smock is snug at the bust – making less fabric to bunch up beneath your gown in the bust area. There are no drawstrings at either the neck or wrists nor any gathering anywhere. You want a smooth fitted finish at the neckline ideally. The shift may or may not (your choice) be cut with gores inserted in the side seams from the hip to hem. You can machine sew your shift and finish all visible areas (neckline & wrists) by hand.
