Agree with @LetterI know the others are also small but my gut says Boston is not your best bet.
@parisistherapy , The Short Hills boutique gets mixed reviews on TPF. I would think these are pretty local. You can read a few pages on those threads to get an idea.
I’m not an Hermes exotic person. For one, I’m Actually more RTW focused and i don’t want to spend that much on a bag. But, even with that, I have been offered touch lizard (though by my FSH SA not Madison). But, if I told my madison SA I was interested in exotics, I don’t think there is a shortage. Particularly if one wanted a K28/B30
Those are considered larger sizes these days, and so long as Madison has larger sizes, one can get a larger size bag offer, esp in the higher exotic price point, without much hassle.
