The knee jerk response is generally leather does not count towards prespend in the US or Asia
But, my answer to you could be yes, no, or it depends lol
Did you walk in cold and get a B40
were you introduced to your SA or just have instant chemistry
i am assuming you are not a long standing client bc of your post?
i have a solid rapport with my SA, but my DH has a better one
and, his text inquiries re mens RTW and accessories or life in general get a much faster response.
In my opinion only, if the smaller items that you want are men’s items, and
if your SA looks upon you as an ideal mens client, then I think your foot is in the door*
At any rate, in the US, prespend is not set into stone. If your next bag is also a larger size,
you may already be top of mind. This is bc smaller sizes are currently more popular. But, the larger sizes are also not as frequently ordered by the boutique. JMO though
ETA: *I apologize for making the assumption that a member who prefers a B40 is a male client,
or that men in general might have an easier time getting the QB of their choice. Similar posts have been roasted
for their un PC assumptions.
I do not intend to offend by this assumption, and would gladly accept correction

I will note that my SA is sometimes confused bc I shop both mens and womens RTW ( I am a woman)
and sometimes I feel like asking if my propensity to shop both gives me any kind of leg up lol
i would also like to note that bc of the marked preference for small sizes, it may be possible to get amazing deals lower than retail on collector quality bags in larger sizes. if you are at all interested in resellers
