With separates' fancy arrival on the bridal fashion scene this year comes an even more exciting down-the-aisle development.

The trendlet

Pants - in skinny, cigarette silhouettes; wide-legged shapes; and chic jumpsuits - are becoming increasingly acceptable as part of the bride's ceremonial weekend wardrobe: for rehearsal dinners, receptions, and post-ceremony brunches. The bravest of brides are taking vows in britches.

Where's it come from?

America's obsession with fairy-tale weddings has never included pants as part of the sartorial equation (even in the 1970s, when pantsuits were at their style peak) until now.

However, it's looking like a few well-placed pairs have the potential to change how the world looks at bridal attire - much the same way in which Queen Victoria's choice of a white lace gown in 1840 cemented the hue as the preferred bridal color for more than a century.

A few fashion factors are at play: Pants, especially jumpsuits, are trending heavy on the special-occasion scene, and bridal trends are taking their cue from ready-to-wear.

More women are opting for an elaborate ceremony gown and following up those frothy, beaded dresses with casual, dance-friendly looks.

And lots of brides - many of whom are a part of a same-sex union - prefer their outward ensemble to better reflect the gender with which they most closely identify.

Who's wearing it?

For the time being, matrimonial-appropriate pants are the domain of the most fashion-forward brides - and even for them, not likely for the main affair.

In September, Amal Alamuddin wore a Stella McCartney jumpsuit during her civil ceremony joining her and George Clooney. And in November, Solange Knowles quickly changed into a Kenzo jumpsuit - complete with cape - after exchanging vows with Alan Ferguson.

Would Elizabeth wear it?

I'm not 100 percent sure I would be able to give up my impulse to wear a princess-style halter gown on my wedding day. Still, a Halston-esque pantsuit with a pearly heel and a fascinator-style cage instead of a veil would be the epitome of wedding-day chic.

Should you wear it?

If pants speak to your inner bride, then, yes, go for it! But the fabric of your separates - whether eyelet, silk, cotton, or leather - needs to be a true, optic white to keep your look wedding festive. Yes, a variety of shades, including ivory, dusty rose, and slate are popular colors in bridal fashion now, but if you want to stand out at your wedding, your nontraditional look should be a traditional color.
