20” across the front from each under arm seam of the attached sleeveless shirt under the oversized attached top. 35” long from top of shoulder at neck line down to bottom hem. 8” side slits for added comfort and fit. I have laundered this. You do not need to dry clean as tag will state. It does need to be washed on gentle, hung to dry and finished off on low heat, gentle tumble in a dryer. Linen appearance and feel but is actually 100% Vintage acrylic. Fabric is woven with a tropical imprint throughout. Smoke free home.
