If Erin Fetherston's third collection for her ERIN line were a film, in an ideal world it would be "like [Franco] Zeffirelli directing A Midsummer Night's Dream that stars Mia Farrow," she explained at her Milk Studios presentation this evening. Fetherston incorporated more daywear and separates this season, whipping up butterfly-print charmeuse shorts that were just as flirty as her signature feminine frocks, and a silk collared blouse with delicate lace overlay. A mod shift dress with a graphic floral print was dubbed the "Mia dress." Fetherston called another one of her favorites the "cha-cha dress, because you just want to do a little dance in it." The cha-cha dress has a tassel and beaded checkerboard pattern, and would look terrific on the designer herself. Fetherston is, after all, her own ideal customer—the Spring lookbook even features a model with a pixie cut that is part Farrow, part Erin.
