I need a style.

After reading my last post, I realize I don't really have a "style".  I'm sure Clinton and Stacy would have a field day with me.  I want to dress cute.  I want to look good for my age.  I want to have a sense of style.  I'm just not sure how to do all of that.  My "style" is casual.  My last post is a perfect example of what I wear on a day to day basis.  I'm trying to add some color into my wardrobe.  Hence, the rose colored t-shirt from Old Navy.  And I recently bought these Christian Siriano wedges from Payless.  But I feel like I'm losing the fashionista battle.  Ugh.  When the weather was cooler, I was rocking some skinny jeans and brown riding boots.  But it's March in Florida, and jeans and boots weather is pretty much gone until maaaybe, November.  So what's a girl to do?  Anyone have any tips? Or want to throw out some suggestions?  I should probably start scouring pinterest for ideas.  That place is a total time suck but I love it.  ::skips off to pinterest and polyvore::
