That other, new addiction...
I think that this is a reasonable pledge. I too love to shop and really, I am not motivated by whether or not I have enough clothes. Of course I have enough, I have enough for a small, (really tiny) army. :) I just really love new clothes and shopping and I love the way I feel when I buy something beautiful. One of the things I do that has really helped me keep this from becoming a financial issue is that I love buying things at second hand stores. I love the chase, so this makes it even more enjoyable.
Yes, I've found that I love the chase, too. I love finding a pair of Ms. Me jeans that fit perfectly (usually a little long because I have stubs for legs) and I get to buy them for $40 instead of $110 retail.
I also make a list (I loves my lists) of things that I want to add to my closet. I want a pair of black boots. I want a couple of more nice shirts. I also make sure that anything I buy goes with more than one outfit.
OP - There are definitely ways to enjoy shopping and not have it become a transfer addiction.
I shop way more often now that I can actually find cute clothes that fit... but I am an avid thrift store shopper and love a great bargain! One of my favorite tricks is using the consignment store... I give them the sizes I've grown out of, they sell them and put my cash in an account where I can go shop for smaller sizes at their store and not spend a dime. Then because all my clothes came from the consignment shop there is a really good chance they'll take them back when I'm ready for new sizes and the cycle continues!
You have totally nailed exactly my shopping issues too. I don't think I can even take the June pledge because I do legitimately need smaller work clothes. At the same time, I haven't yet worn some of the new stuff I've gotten. I don't want to have to give them away with tags still attached.
Damn these transfer addictions!
