If I where you I would think about hiring out waistcoats and matching ties/cravats. Also dress shirts. My son who married last September consulted with his friends and they all decided they did not want to wear suits for a wedding in Turkey. My son was marrying on the beach and it seemed it was going to be hot and suits would be over dressing. The all wore dress shirts, waistcoats, cravets and linen trousers and light coloured shoes. We note a lot of weddings in Turkey where the groom, best man etc., do not wear suits. However, there are Scottish Weddings and kilts are heavy, so you might think about kilt hire too.
