Proms run May–July. Buy by April for the full size range.
Buying notes
- Fit beats fashion: a well-fitted £60 suit looks better than a baggy £150 one.
- Slim and skinny cuts are standard for prom. Check the chest measurement against the chart.
- Hire can beat buying for a one-off, but bought suits resell well on resale apps.
- Order early: prom season runs May–July and the popular sizes disappear from April.
