Two different dress patterns, One uses #0 & #6 needles and fingering yarn the other #2 and sock or fingering. One is a tube type dress, the other a more traditional style. Both have been tested but I am on AG knitters several times a day if you need help. I haven’t said how much yarn because both were knit from stash and take very little yarn tho I am unable to give an estimate.
You might use some thin ribbon or other decorations.
