Wearing a bold print gets harder as you get older. It's safer to stick to subtle prints or block colours. I have always found prints quite tricky. My daughter Carly, who is on the design team at Stella McCartney, is obsessed with them.

I prefer 100 per cent cotton Ts. They are kinder to lumps and bumps than figure-hugging stretchy Lycra ones and feel nicer against the skin. Extra-long-sleeved T-shirts are a lifesaver for me. I wear them either underneath a shirt with the sleeve pulled out of the cuff, or underneath gypsy tops, tunic tops and waistcoats.

Fluted sleeves or any sleeve that flares out before coming in again at the wrist are very feminine and a great way to distract from the dreaded 'bingo wings.'
