I am in Human Resources and DH is an engineer. We have financial conferences once a quarter and re-adjust if we notice we are dipping into our savings or not putting enough into our 401Ks.
Other than that, we both have "fun" money accounts and as long as family birthdays and Christmas presents are covered, no one questions if I spend my money on shoes or bags or clothes.
That said, I only have a few pairs of CLs in my designer shoe collection. I love Loubies, but I have a tendency to buy what I like and sometimes I buy Manolos, Jimmy Choos, Diors, Zanotti's, etc...whatever catches my eye and I think is beautiful.
