Grey Babaton Stedman Jacket Size Small

Grey menswear jacket, probably bought in 2019. Just dry cleaned 2 days ago but shows some dark grey/light black discolouration. I have no idea what it is - maybe from friction against a black purse. It’s a lovely jacket even with that though and it’s actually not really noticeable once on. Also I’m definitely a medium and this fits me great so keep that in mind also - if you’re very small, this will be too big.
