Summer means sun, but it’s also got it’s fair share of corporate parties, family events and often weddings that you’ll have to attend. Be The Best Dressed. A classic black or grey suit is great for a wedding, but don’t be afraid to switch it up. A punchy blue suit still looks smart, but will stand you apart from being mistaken as one of the groomsmen. Cotton or linen should be your choice of material if it’s an outdoor setting. Think of suits as two separate pieces – and they won’t just sit in your closet, waiting for a special occasion.
