I'm obssessed with youlookfab.com - a great style blog where you can post your outfits, purchases and show off your style. But the cool thing about this site is that if you're stuck in a rutt, or over-spending on new items that you may like but not love, then this is the place to be.
You will get opinions on everything from how to wear an item of clothing, what may or may not look good, trends (etc.) and general support of the youlookfab community. I highly recommend this place for all those who love to shop. And, it's just plain fun.
