Mango Suit Collection sleeveless sheath dress and jacket

I bought this in S. Africa on a business trip. Wore the dress twice (so no tags); never wore the jacket (so has tags) because it was warm there. Selling together, because that is what makes sense. It's a gorgeous set! Material is stretchy with a tweed pattern in grey. Dress is labeled size US10, jacket US M, but it's not sizing I'm used to. I liken the sizing to a WHBM size 8 or even 6, snug on me (but I wore the dress anyway). Probably best to use measurements. Dress laid flat: 15" at the waist; 17.5" armpit to armpit; 30.25" armpit to bottom hem.
