Sweet vintage spring floral dress northern traditions size M

cute little spring summer airy dress with a dark navy background and purple flowers. missing the button at neck, but comes with an extra. I can't find the fabric tag but I'm pretty sure it's polyester, but it's two sheer layers so quite breathable for warmer weather. can be dressed up for formal events or grunged down for informal events! bust 17" waist 18" length 33"
