I'm *still* researching what Goyard St Louis to get!! If you're in that forum you can see I've planned to get it this August, then this December! At least I am finally buying it next Monday after I kid you not YEARS of debate and research. I went to NYC in August to finally check them out in person and left without one still. Luckily NYC is only about 80 or so minutes each way for me so it wasn't too crazy and we spent a gorgeous Saturday exploring the city.
Generally when I want a new bag or shoes or the like, what I do is create a reasonable budget in my paycheck for it. I get paid weekly, so every week I might put aside $25 into my "fun money savings" account (separate from actual savings for the future and emergencies) so that way, it's not too painful to save up and yet it does add up quickly. By the time I've saved for it, I firmly know that I still want it OR the desire has passed and I just move that money over to my regular savings.
My one "crazy" time was probably the time I spent my entire Christmas bonus on vintage LV luggage, however it has really paid off. I use it every chance I get and it's absolutely gorgeous. My mom shook her head at that one but I think she's happy about it since I have no issues letting her borrow it!
