The Cosmo Dress is a playful cut-and-sew knit dress with milkmaid style sleeves and a sexy slit in the skirt.
It’s a great pattern for bright fabrics, colourblocking or neutrals. This easy-to-wear style is classy enough for cocktail bars and sexy enough for a hot date.

The Cosmo has a flattering gathered bust and a firm-fitting bodycon cut. It is "pull-over" styling, so it has no zippers or buttons to worry about. Fit it to your body and it will give you a "spanx" effect, exaggerating your natural curves.
