I think I would choose one that is quintessentially Hermès such as Brides de Gala. I think there is a scarf with a lot of squares with that design in mini versions in lots of colors. I'm not sure if it comes in 100% silk though.
which is the most universally appealing scarf/colorway do you think? i'm getting one to donate to dd's school auction and obviously want it to attract more than one bidder.
How about De Passage a Paris in the red/white or blue/white colorway? Not quintessential Hermes but it's very French and blue or red looks good on everyone!
How about Bolduc? That is blatant Hermes. The orange/brown one may still be found lurking in some stores, but it's not a colorway that's suitable for everyone.
