Ordered both Cornice (long) and Arctic Gemini to wear over a suit. Both designs are very similar so returned the Cornice because if I'd ordered the removable fleece separately, it would have worked out more expensive. Arctic Gemini is shorter in length but suited my husband who's not very tall. In fact, fitted son-in-law who's 5'11'' so he nabbed it straight away and I had to order another one for my husband. Both very pleased with my selection.
If you are looking for a jacket to wear over a suit, this one or the Cornice fits the bill perfectly. My husband has taken the fleece (not the outer jacket) with him to Italy as the evenings there are still a little nippy. He has been wearing just the outer jacket over his suit in the UK, and is happy that he doesn't need to carry an umbrella, which he frequently loses.
