Short answer
Spring weddings suit mid-weight wool or fresco blends; summer wants high-twist wool or mohair blends that resist creasing in heat; autumn returns to flannel and mid-weight worsteds; winter is flannel, tweed or cashmere blends under winter light. Weight and weave decide how the suit survives the day — and how it looks in every photo after.
Spring and summer
From roughly April: high-twist wool (the “travel” cloths) for resilience in heat, fresco for open weave, mohair blends for subtle sheen under strong light. The summer wedding suit must survive a full day — ceremony, photographs, dinner, dancing — without the knees reading the schedule; that is what weave buys.
Autumn and winter
From October: mid-weight flannel for the soft, matte photographic texture; heavier tweed for country weddings; cashmere blends for the city wedding in the cold. Winter light flatters deeper colours — the mid-greys and blues of summer can read washed-out in January; the fitting conversation includes the venue’s season directly.
The cloth conversation, in practice
Bring the venue, the date and a photo of the dress fabric to the fitting; the tailor shortlists three cloths with cuttings to hand — see the cloth guide for the full vocabulary. Colour is agreed with the couple; weight and weave are agreed with the calendar. Never let either decision be made by a photo on a phone screen.
