Calculating how much fabric you need For a longer adult-size dress with long sleeves you will need a minimum 2 to 3 yards of wide fabric. You also need to take account of the width of the fabric. As a rule of thumb most fabrics come in 45 inches in width but you may find some 60 inches wide.
Cotton jersey knit blended with some Spandex can provide even more structure and is ideal for form fitting maxi dresses like the one shown. 100% Cotton jersey knits are ideal for oversized or flowy maxi dresses.
Maxi dresses rest at the ankles and are also known as full-length dresses or tea-length dresses.
A maxi dress that gently flares from the waist can highlight your curves while downplaying any trouble spots. A scoop or v-neck is flattering, drawing the eye vertically rather than horizontally. And you can add a high belt to create an empire waist, lengthening your legs.
