Ladies, thank you for your suggestions!
bj1111, JR - I'll keep it slim, thanks!
Jenava, rachylou - lovely idea! I'll have to go for a sweater and thick tights though, it's really cold here
Inge - wonderful suggestions, thank you! The cape hits me slightly below the waist, it creates an A-line silhouette but it's quite voluminous, so I'll probably have to stick to really slim bottoms.
Today I wore it over a black shift dress with a burgundy cardigan (with white dots), burgundy tights, black heeled oxfords and a mustard scarf. I'll try to take a photo, but I still can't post it
