est. = guide price from the retailer's listing, not a live price. "Checked" shows when we last saw the price at the retailer.
Leavers’ events cluster in June–July; order 4–6 weeks ahead.
Buying notes
- Year 6 leavers’ assemblies are smart-casual at most schools. A two-piece and shirt is enough.
- For Year 11, treat it like prom: fit first, then budget.
- Ask the school for the dress code before buying anything formal.
