Pedicures. Manicures. A new purse every 4-5 months. New earrings now and then.
An amazing hairdresser every 5th week for toner, color, cut, comedy, therapy. (very worth it)
Puppy toys for Cedar.
Good wine, good friends, and appetizers on Fridays.
A good vacation once per year.
I believe I'm flunking this thread's idea. However I haven't stopped any of my high maintenance habits because we haven't been in a money pinch yet. I don't believe I've changed any habits despite the economy in general. I'm otherwise frugal, I have no habits like smoking/etc and always put my kids first buying their new clothes, school needs, lunches, whatever. I go to work, hubby does too, pays cash for everything, puts money in the bank for college funds and savings accounts. If we feel a pinch, those will carry us through, I suppose. I remember to count my blessings.
I'm prepared for the endless bashing of the non-princess types... (live and let live).
We did give up satellite/cable tv. I think it is a waste of $$.
Edited to say: Oooops..... it said ONE indulgence. I just re-read it. I did flunk.
