Looking for some ideas please. We're going to a wedding in Europe in July and it'll be about 30 degrees. My husband is struggling to find something to wear. He's 34, quite overweight and he's very conscious of his belly i.e. he doesn't like to tuck shirts in. If we were at a wedding normally he'd wear a regular suit, with a waistcoat over the shirt when he took his jacket off in the evening.
He's struggling to find an outfit that ticks the boxes of formality, comfort, suitable for heat, and style. For example, he would like maybe linen trousers with an untucked shirt but is struggling to find a shirt cut that doesn't look sloppy when untucked. He quite likes colour and patterns and is open to various fabrics.
