As the title says really and here is the blurb from their website: -
'...T.M.Lewin formal suits are made from the finest Merino wool using traditional Savile row techniques. The linings are 100% Cupro. The single breasted suit jackets come with a double vent, sloping pockets and 4 kissing cuff buttons. The trousers have a zip fly, a single pleat, one back button pocket and belt loops to fit a 1 belt. All T.M.Lewin suit trousers are supplied with an unfinished inside leg so they can be tailored to the perfect fit. We can carry out leg hemming to the length specified by you for free or supply the suit trousers unfinished...'
These suits are very good quality and the sizes go up in ones (32", 33", 34" etc).
