Someone asked me recently what his first two proper, business suits should be. Here’s my opinion.
The two most useful and fundamental suit colours are navy blue and mid-grey. They go with the greatest number of shirts and ties, can be anything from casual to wedding attire, and suit most skin colourings. If you want variation, one of these could be in a pinstripe. Make sure the stripe is not too bold or too close together. Avoid checks, at least to start with.
As to cloth, both should be wool. Cotton and linen are summer extras, and there is no need for cashmere or silk blends. The average weight of wool used in suits is nine to eleven ounces.
For some variation between summer and winter, I would recommend one lighter weight – perhaps seven or eight ounces if you can find it – and one heavier – more like twelve to fifteen. Flannel is a nice alternative, but would be too heavy for half of the year. (The vast majority of wool suitings are worsted, which is wool that has been combed and flattened to appear thinner and crisper. Flannel or woollen suitings are not combed and are thus rougher.)
Ignore the “super” wool numbers. This refers to the width of the wool’s individual strands – the higher the number, the thinner the strand. Thinner wool is more delicate and more expensive, but also less long lasting. Anything around super 100s or super 120s will be fine to start with.
