This Universal Standard tunic is so lovely to wear in warm weather. The fabric is lightweight but not flimsy. Typical of Universal Standard clothing, the stitching and details are impeccable. There are snaps between buttons so it won’t gape at the bust line. The cut is loose, so it could fit a 30W. I wear it when I have a sleeveless top on, and have to run out of the house or if I’m going to be sitting in AC. Universal Standard size XL which is equivalent to a 4X US.
