This is an Edwardian tambour lace jacket with raised applique roses. It dips at the front and is raised at the back with a small stand collar. Long sleeves with pointed cuffs.
Bust measures 34ins, back neck to edge 16ins. I would say that the size is equivalent to a contemporary UK size 8.
There are some small pale brown age marks including one on the right upper sleeve, apart from this excellent condition.
