The classic suit is becoming a stylish alternative to the wedding gown for some brides. Like the sheath it's long and columnar only in two-pieces with a jacket and straight skirt. There are of course exceptions. Skirt shapes can be flared like A-lines or take on full bell contours even under man-tailored jackets. Pantsuits are another option with pant legs varying from slim cigarette widths to wide culotte cuts.
So what differentiates the wedding suit from the everyday business suit? Typically, the fabric in a wedding suit or coat will be special. Considering the season, winter for example, peau de soie and brocade are luxe, heavier materials that sculpt to the body well and hold their shape. A high quality wool suit fabric can go any season. Imagine a wool crepe suit in white or ivory, lined in a lightweight pure silk; it will have a totally different appearance than what you wear in the office or boardroom. Linens, and medium weight silk shantung or dupion have just enough weight to tailor well and look chic for spring-summer weddings.
