I definitely think that some jobs make it harder to shop seasonally (if you are in retail or the fashion industry, like you, Lisa, or Kkards, or Angie -- or if you are always walking past stores, like Christina or those who work inside terrific malls. I would be very tempted to shop all the time in that situation. Though I might still separate "shopping" (i.e. thinking about it, planning, making my lists) from buying. Even for someone who's regularly on the floor of the stores, it can take a few try-ons to decide, yes, this is the item I really want to take home with me.
Also, I want to reiterate -- when I was building a wardrobe, I shopped ALL. The. TIME. And while it wasn't great for my finances it was really the only way I could build up my wardrobe, and even then it took about 3 or 4 years.
Laura, this is where I really "get" what you are saying. Until I had a great set of essentials in my main neutrals, I was forever buying stuff that was "less than" ideal. Now, it's much less frequent because I don't have as many wardrobe holes. So even if I develop one, I can cover it with another item for a while.
Fashintern, yes -- style your closet has an entirely different connotation to me -- it is not a shopping ban but an invitation to wear what you have in new ways and rediscover things that you might have allowed to languish. Which many of us do, even with the best intentions!
SarahDB -- it's the headspace issue that is really important to me. I want to love my wardrobe and have fun with it and wear my clothes -- and I actually enjoy shopping now (never thought I'd say that) and find it somewhat therapeutic and fun! -- but I also want energy to devote to other areas of my life -- so I want to be able to get on with it.
