You know the rules...tights and a light cardigan for Spring, awesome wedge heels and lighter toned accessories for Summer!
My favourite dress from the collection above is the ice blue one on the lower left (Forever New $44). It has such beautiful details on the bodice with the eyelet fabric, and then the skirt is soft, flowy and feminine. For Spring, I would pair it with a charcoal or plum sweater, tights and flats. For Summer, wedge heels and a long side braid or loosely swept hair.
