Puddling
Puddling goes beyond a simple break. It moves into a sense of excess. It can look very formal or just the opposite, depending on the fabric.
For a relaxed feel, use a soft, gauzy fabric, which won't look too fussy if left a bit unkempt at the bottom. Much like the difference between a break in faded jeans versus a break in suit pants or dress trousers, one kind of fabric will look casual, another stylish. Fabric and style work hand in hand here.
