Is it possible to buy a suit for an 8 year old boy?

[clumsymum]

Without having to go to a bespoke tailor (cos that's too expensive)?

yes - BHS as suggested (in their wedding section) or somehwere like this - places that do First Communion stuff often have suits.
Or if you only need it for a day, Moss Bros etc hire out child-size suits.

Terrific response, thanks.

We're going on a cruise in April, and ds needs a suit to join us for dinner on 2 or 3 of the nights.
