The clothes rut is as big as the food rut for many men. We find something we like, and buy it again and again. Blue, grey and brown become the only colours in our wardrobe. Our most exciting purchase of the year is often yet another polo shirt. Well, as it's time to invest in a summer wardrobe, here's a challenge. Buy one of each of footwear, trousers or shorts, tops and accessories in a style or colour you've never tried before. Just looking for something different will expand your sartorial horizons. Whether it works or not, you'll have learned something about your look and it needn't cost a fortune.
