Jenna Dewan-Tatum was the icon for the oversized sweater / cardigan this winter. Now that the weather is warming up in LA, she's swapped the heavy cardigan for a lighter version. She's teamed it with leggings or jeans (I can't tell) and brown suede boots.
As far as patterns go, I'm not usually a fan and Jenna's open cardigan is not winning me over. While the style of the cardigan is on trend, the pattern looks like it belongs in the 90's. The simple white shirt / tank and long necklaces are a nice touch though.
