Sainsbury’s has been caught by Royal Wedding fever and has designed a celebratory t-shirt in honour of the couple.

The t-shirt, available in stores for £10, is designed in line with playground song ‘Kate & William sitting in a tree, K.I.S.S.I.N.G’

Sainsbury’s said the t-shirt is the “perfect way to honour the momentous occasion and guaranteed to be the talk of the street party”.

Sainsbury’s will also unveil Royal Wedding mugs and all the accessories needed for a party.

Sainsbury’s seasonal buyer, Kate Haworth said: “We know people want affordable keepsakes, and that’s exactly what we’re offering.”

Other retailers have already got into the Royal Wedding spirit. Tesco brought out Kate Middleton’s engagement dress and Asda unveiled mugs.
