Camouflage is a style that has been able to avoid the cyclical aspect of most fashion, and year in, year out, it is now a staple of many wardrobes.

Florals have always been big news in women’s wear, but in men’s wardrobes up and down the country, the trend is increasingly being seen. The well-dressed guy obviously has no chance of preventing a flowery motif for his summer look, cropping up on ties, shorts and jackets. In a discreet, masculine way, a short-sleeved floral shirt worn open over a simple t-shirt and paired with light-colored trousers or chinos is a fine way to follow the style.
