I went on a day trip out and saw a lady with a chest sling bag sand/ beige in colour . (The type that are a bit like a mini back pack)
it looked very good quality. (Not leather) she didnt seem approachable so didn’t have the courage to ask (!) (really wish I did now)
The only identifying marker I could see/ remember on it was a very small / slim silver flat rectangle shaped tag on it (assuming the brand name)
Similar (ish) style to picture - metal tag marked in red on position of bag)
I know this is a very long shot thanks to my poor description - but you never know!
Thanks!
