I keep telling my clients that as you grow older make not only life but your look clean and simple. Wear classics, changing the color with fashion but staying within the palette as to what looks good on you and goes with the rest of your closet. Keep " bling" or "out there looks to accessories, that way you have a closet that has exactly what looks good on you and you alone, but you can up the fashion factor with your accessories.
  I love the book "Parisian Chic" by Ines de  la Fressange. She is so classic in her  look she just changes things  up with color and accessories. Here is what I am talking about, see what little effort she uses to make herself look current and yet you know who she is. 
 
 
 I peraonlly love bling, and right now I am more than a little in love with these big bid necklaces or statement pieces of jewelry as I think they really spark up an otherwise classic look. I do know however, that as you get older bling needs to be handled very sparingly. It certainly should not be worn head to toe, chose one piece of clothing or jewelry to make the statement and then walk away. There is a great blog to look at called http://advancedstyle.blogspot.com/. You need to check it out, I will tell you however, that there a very few of us that should try to copy of these looks. These women know what they are doing and they are great, but few of us can carry it off.
 Go ahead and wear bling just remember chose wisely and sparingly.
