Lovely 100% wool suit, nice fit, cool and light weight as you would expect from a wool suit.The trousers are elasticated so allows for a little movement between waist sizes.Be aware the suit chou jacket pictures on the Atelier-lumieresShops website are a little misleading as some photos show a plain black lining and others show a pasley effect lining, and two different models modelling the chou jacket.The actual lining is pasley.I am a 48" chest and the 48" chou jacket and waistcoat fitted perfectly.
