Get the whole geek schoolboy look in one order with this five-piece fancy dress costume set - a black blazer, matching trousers, a striped necktie, a badge-print T-shirt and a pair of glasses all included, so there is nothing else to source before the party.

The suit: a plain black blazer with a front button fastening, paired with matching black trousers on an elasticated waistband for an easy, comfortable fit.
The look: a blue and beige diagonal-striped necktie that fastens at the back with a zip and hook rather than a real knot, plus black-framed glasses with a clear plastic lens and no prescription.
The finishing touch: a black T-shirt printed with a mock comprehensive-school crest across the chest, worn underneath the blazer for the complete class-swot silhouette.

Perfect for:

Halloween parties
School-uniform and throwback theme nights
Stag and hen dos
Book character and fancy dress days
