I have recently become a big fan of J. Crew which if you would've told me that 5 years ago I would've said NO WAY TOO PREPPY! It seems as though in the last couple of years their style has become much cooler and chic and a lot less East Coast prep school style. I love their dresses, shoes, and especially their jewelry. I have never been a big fan of costume jewelry but slowly began incorporating pieces into my outfits (yes even now with a baby and one on the way) and it makes such a huge difference!
I love adding either big earrings and maybe a few gold bangles or several long necklaces and small earrings; however I try not to over do it because then it just looks silly. I also love thick bracelets and beaded cuffs. I once got a great jeweled cuff at Calypso. Check out these strand pearl necklaces from J. Crew. I picture them with a cool white or bright colored linen or light fabric button down shirt with jeans and heels or a nice T-shirts with cute shorts wedges and/or heels.
