A fashion designer is responsible for designing clothing or accessories. The designer will be working toward a brief, starting with researching current colours and trends, through to hands-on design of the garments, fit sessions and sampling. The designer will also sometimes be in charge of selecting fabrics and trims for their area.
A graphic designer is someone who works very closely with a fashion designer to create any placement prints (one large image on a garment) and all over/repeat prints (a smaller design which is repeated over the entirety or large section of a garment). They will be designing graphic images/typography to go onto the garments as well as washes and effects for fabrics and embellishments.
