There's a puff-sleeve personality for everyone, according to the runways. Maybe you'll like yours neat and rounded out at the shoulder for autumn (see Givenchy), or maybe you'll want something decadent and entirely inappropriate for anything that involves dipping sauces (see Emilia Wickstead's gigantic-sleeved floral dresses). Whatever route you choose to go down there is a huge amount on offer from edgy to prim.
Experiment with elements of design like shape, form, silhouette, proportion, texture, pattern and colour. In fashion design process the term silhouette refers to express the overall shape and volume of the design. Silhouette is one of the most important design considerations and it is easy to overlook when working on paper in a two-dimensional context. Designer gives the perfect silhouette from the front side and from the back side or side view. It is the meaningful relationship between garment and body like A-line, I-line, V-line, two tiered silhouette etc.
