It is so much easier said than done, but really? How could you not? If you set an expectation and an idea of what you really want, then you can start bargain hunting...and the bargains will just appear!
You won't know it until it happens, but you will be out one day and see something that makes you say, "wouldn't this be good as ____ ."
for example, when i was at the outlets with my MOH, we were in a store and I found a cute headband. I jokingly put it on and said, "What do you think of this?" Her response was "I think that'd be perfect for your hair at the wedding!!"
Of course, she was right and I had to purchase it. The best part, it was only $13!!
Wedding hair piece - done!
