With a focused edit of 16 fabric collections for the summer and a further 16 for the winter, you are spoilt for choice: options range from super fine wools and soft flannels to breezy seersucker fabrics for summer suiting and heavier weight flannels, eveningwear and velvet for winter.
This choice is a matter of weight, occasion and pattern – lightweight (typically 8oz-9oz), heavyweight (14oz-15oz), or something in between. A 12oz is good trans-seasonal choice. Of course it is also a matter of colour, weave and pattern – chalk stripe, bold or subtle checks and so on.
At this stage you will need to select the level of construction required - half-canvassed or fully-canvassed. Full canvas suits are constructed with a layer of horsehair canvas under the wool fabric to offer shape and to ensure an elegant drape. In a half canvas suit the layer of horsehair only runs through the chest and lapel of the jacket. This option is usually less costly, lighter weight and can be cooler.
