Lungo L'arno Linen Jacket Natural Cream Eyelet Detail Lightweight Medium?

Lungo L'arno Linen Dress Natural Cream Eyelet Detail Lightweight Medium? No Size Tag, but when compared to similar pieces I think this is a medium. Please check measurements. Smoke free home. I do have pets (dogs and cats), but all effort has been made to remove any pet glitter. Items are stored in a room that they are not allowed inside... but you know how cats listen.
