Vintage 90s floral oversized shirt tunic dress loose pink white blue Jacobean

Vintage 90s oversized shirt tunic dress with looose baggy cut and beautiful floral pattern. White with pink blue and green. The florals have a Jacobean vibe and the shirt is just so vintage 90s fun. I think it may have been some kind of pyjama garment? No tags but feels like 100% cotton. The material is a bit thick, like flannel, and super soft No size tags but fits XL to plus size or oversized on smaller. Size 14 16 18 20 1x 2x 3x depending on the look you want Shoulder 18” Armpit 29” Length 33” Very good vintage condition
