Texture is the visual composition of the fabric. Generally larger prints look best on larger body frames, smaller prints on smaller body frames. A loose woven or bulky fabric will add visual weight to the figure. If you are small on top and bigger at the hips, consider balancing your figure by wearing a bulky fabric on the top - where you need it. Keep the smoother less-textured fabric on heavier hips.
Pleasing proportion is a combination of the elements of design, line, texture, color etc.
Proportion is the relationship between the various parts. When you know these facts about yourself, you can choose designs that put you in proportion. Remember, accentuate the positive and eliminate the negative, and most of all, drees in well-fitting clothes.
