Tried and pictured the regular size small. my stats are 34/35a-28-36 and i usually wear a 6 or an 8 on top in shirts and blazers. the small here was nicely loose so it might run a bit big.
in person, the colors are dark navy on light beige.
lovely heavy weight cotton and stitching.
i think it's deliberately a bit short, hit at my hip (i'm 5'6") but i like this.
the 3/4" sleeves are a bit nowhere for me...i wish they were full length but that's my only quibble.
