Lost: denim shirt in Dulwich Picture Gallery gardens

[mrmorris]

If anyone has found a denim shirt with a light/dark pattern (almost chequerboard style) from H&M (size 10 or 12?) in the gardens of Dulwich Picture Gallery please let me know.

It was lost there on Sunday late morning, possibly left on a bench. It wasn't there when I returned 2 hours later, and hasn't been handed in to the Pavilion Bar, Gallery reception or shop.

A much loved item worn almost every day - would be delighted to get it back!

Thanks,

Madeleine
