Ruby Maude slip in Strawberry

Hey, do you know what the markings are and have they ever come out in the wash? Thanks

Thanks for answering! Could you take clearer pictures of the stains, trying to work out whether it’s worth the work as alcohol is tricky to get out. Could you also share the fabric composition? (Apparently that too can affect removal) It’s a stunning dress, shame to not be able to wear it!
