so i made one more peasant shirt. i know i am obsessed, but i think i figured it out this time and it is just the perfect summer top.
for a better fit on this top take out an inch on the neckband. when cutting out the pattern i just pinched out an inch of the middle on the pattern piece like the following picture (1/2 inch on each side). if i were you i would make the front neckband out of some scrap fabric before cutting out your real fabric just to make sure it fits right. this adjustment made all of the difference in this top. on my other two i feel like i am constantly adjusting them because they come down too low or fall off the shoulder. this took care of that.
some design changes i made was adding a ruffle at the bottom of the neckband and extending the sleeves to 3/4 by just adding about 5 inches to the bottom of the pattern.
