Smart, double-breasted Betty Jackson Trench coat / rainmac in Navy Blue, Size 20 (EU48).
Pit to pit measures approx 24.5", so should comfortably fit up to 45" bust (UK20) with room to move.
Length shoulder to hem approx approx 43", so will fall around mid-calf length on most.
All buttons marked 'Betty Jackson Black'. Tie belt at waist. 2 deep pockets. 
The fabric has a silky-feel to it, a bit like a soft-shell material. The coat is fully lined in a satin-feel fabric. 
It is relatively lightweight. 
Very good condition! See pics for more details and measurements.
