How to wear necklaces with sweaters. The normal answer would be to skip the necklaces and just wear a statement earring. In most cases this is true, but if your sweater is a neck or low cut you can still layer the way you would with any top. Here we did one of classic layers, making sure all necklaces are a different texture and length. If we were wearing a sweater that wasn't open we would just go with a good pair of hoops or wearing a long necklace outside the sweater.
