Love this lool with the viral Amazon summer cardigan! Cardigan - get your regular size! I'm in the 22 and it's very generous, I could have done the 18 or 20. White jeans - size up! I'm in the 20 and I love the fit but had a hard time zipping! Top- runs true to size! I am wearing 2X! LTKSeasonal LTKPlusSize LTKStyleTip
