Grandads are often pretty set in their ways so trying to buy them clothes is no easy task. It is easy, however, to update your Grandad's accessories such as belts, scarves and gloves. If you're feeling really generous you could splash out on these Paul Smith sheepskin gloves (£75).
You can also get lots of nice handkerchief sets and you can never have too many of those! This makes a good gift as the prices range is quite varied. I like this Derek Rose set (£15) with paisley print.
Alternatively, slippers are always a Grandad's favourite footwear! See below for more gift suggestions.
