Weddings, Ascot, Goodwood, the Gold Cup; the Summer season is rife with occasions requiring a good suit.
The problem is that these are all events which take place under the English sun (the pale and erratic cousin of the Tuscan sun). While women can coordinate frames so they easily become part of an outfit, men are left battling not to look like an FBI agent or a member of the Mob.
I think the key is colour. If it is sunny enough to need protective eyewear then you should be in a lightweight, summer suit in a suitably light colour. Black or very dark navy may make you look like an extra from Reservoir Dogs.
If blue is your go-to then go for a brighter hue and channel JFK in tortoiseshell. Keep accessories light, a pale pink tie or something in a fun print can be a nice touch.
If you favour Aviators over Wayfarers I would opt for a lighter suit, pale grey with a plain shirt is a classic combination. If you feel like something more adventurous you could always choose a Prince of Wales check.
If that all sounds too dreary for words, fear not, I've saved the best until last. If Cannes and Pitti Uomo are anything to go by, the latest trend is coordinating mirrored lenses to bold coloured garb:
In conclusion, when in doubt go light and bright, wear with confidence, and always have a glass of Pimm's in hand. Happy revelling.
