Vintage 14 fits like Medium made in Great Britain lightweight blazer jacket

Very good used condition, strong shoulders, single button closure. Lightweight and unlined. A beautiful mauve lavender shade of purple. Beautiful lace inserts. One extremely minor discolouration in the lace (see fourth from last photo). Please see photos for measurements - this is a vintage 14, but based on the measurements I have listed it as a Medium. Items come from a smoke-free home.
