One thing I've recently learned to embrace about my 30's is that you know your body. In the past I always spent so much money on clothes from really nice places. Sort of came with the fashion design job that I had. If it didn't quite fit, the label sewn into the back always made up for it. Now I see something and just know that it will look good on me or absolutely horrible without even trying it on (clearly I avoid the latter). The freedom in this is that when I see a shape that I like I go for it no matter where I see it. Wearing something that really fits makes it looks 10 x the price. For example check out these cute suits and peep toe shoes I just got. I did not spend more than $30 on any 1 item. Of course I did not rely on my extrasensory perception. I did actually try them on before buying.
