Finding the perfect wedding dress, according to an old adage, is like finding a perfect partner: You want one that hugs your body, offers support, lifts you up and makes you feel beautiful. So wouldn't it be great to get a dress from a brand that, like your future spouse, you trust to give you these things on an average Wednesday as well as on what's supposed to be the most memorable day of your life?

That seems to be the philosophy behind the slew of major mass-market retailers now offering bridal gowns. It was an idea popularized by J. Crew, which launched its Weddings and Parties collection in 2004 after noticing women were buying some dresses in multiples to use for bridesmaids or in white to use for themselves. The notion then grew to include Isaac Mizrahi's Target dresses, Viktor & Rolf's design for H&M and others.

The trend seems to be exploding now, tapping today's market of more budget-conscious brides with gowns from the Limited, Ann Taylor and White House /Black Market. Next spring, bohemian brides-to-be will be able to sift through Anthropologie's wedding gown selection, while discount divas with their eyes on luxury names can check out Vera Wang's designs for David's Bridal.

And there are lines like BCBG Max Azria, which doesn't have an official bridal line but has figured out why its loyal customers are fighting over the last off-white column strapless dress in their stores. The company has added to its website a "wedding shop" dedicated to its more formal dresses, including white ones that can pass for bridal gowns.

"These gowns are completely specific to their brands," says Heather Levine, fashion editor at wedding website TheKnot.com. A wedding gown from J. Crew "has the same vibe as any piece in the store," she says. "These companies are creating designs in their own brand. You're getting the same product from (these stores) as you would from your local salon boutique, but what it really comes down to is your style. If you want something really over the top and ornate, you're not going to be shopping at these online retailers."

J. Crew doesn't break out wedding dress sales from its overall revenue, a spokeswoman said. But the company has seen enough business to add five or six new designs each season, and it opened a full-on bridal store in May in New York. It also has in-store salons with limited selections at outposts across the country.

BCBG Max Azria usually has items in stores, but, for the most part, the mass market gowns are available only to brides embracing the Web, but Levine says shopping for them online shouldn't be a problem.

"While we would never recommend buying a couture gown online, these gowns are more true to size, so that you can feel more comfortable about making that purchase online," she says. Plus, she says, you'd probably have to make alterations — like sewn-in bras for added support — to boutique store gowns, too.

The mass-market phenomenon is more than just a case of brand loyalty. Brides spent an average of $1,134 on their gowns in 2009 (making this an estimated $1.7 billion annual industry), according to the more than 21,000 couples who answered TheKnot.com's annual survey. Dresses from these mass-market retailers can go for less than half that.

"We are back-peddling away from this wild fashion party that we've been enjoying until the recession hit," says David Wolfe, creative director of New York trend forecasting firm Doneger Group. "Everyone recognizes that people are not willing to go into massive debt for a wedding dress. ... We have a lot of young women who don't want to dress in a really establishment kind of label. It's sort of modern, hip and cool to dress in your favorite everyday wardrobe."

He adds that in the giant retail landscape of bridal wear, these trusted brands offer a jumping-off point.

"If you know you're an Anthropologie sort of girl, then that's where you're going to gravitate," says Wolfe. "Those brands have their own integrity."

But is a reasonably priced, easy-to-buy dress too good to be true? We asked some brides-to-be to give some samples a test walk down the aisle.

J. Crew

The brides loved the look and feel of the lightweight, casual J. Crew dresses — even if the prices can be a bit higher than the ones from other brands (this season's dresses run from $225 to $3,500). Most of the dresses showed a lot of arm, but some of this brand's full-length dresses also had a bit of sleeve for those who want something more conservative. J. Crew and the Limited were the only brands to take a stab at a full ball gown. For Nicole Urso, 29, we went for the silk tricotine goddess gown ($475, up to size 16) which, though comfortable and lightweight, would need a bright sash, fun accessories or other splash of color to liven up the simple design.

White House/Black Market

A modern choice for the retailer's sole current entry in the bridal gown category, this number with a sexy raised hem was a hit with the brides with strong personalities and came as a surprise to those who'd written off the brand as a bit staid. For every reference to model/actress Stephanie Seymour's frothy mini in Guns 'n Roses' "November Rain" video, there were exclamations of delight about the form-fitting bustier, seemingly quality material and sexy look that showed some leg and decolletage. Gina Lanfur, 43, who modeled the gown, says she liked its romantic, soft, easy drape and price tag ($498, made available up to size 16). However, the structured bodice with boning means that bustier brides might have to go up a size to avoid a not-so-sexy "cup runneth over" disaster.

BCBG Max Azria

The brand's selection of unofficial wedding gowns includes somewhat conservative items like this season's one-shoulder silk Grecian dress ($358, up to size 12). For 37-year-old Robyn Eckard's second wedding, we chose a sexy, low-back, pleated floor-length gown (up to size 12). When accompanied by the right accessories, it gave her a vintage Old Hollywood style. That isn't to imply it was constrictive: The soft nylon and spandex material allowed our bride the breathing — and eating — room she'd need on the big day. The bill came to $398, a little over half as much as the $750 gown she's already purchased at David's Bridal.

The Limited

Though we appreciated how well the full skirt flared out on the ball gown (also $298 and up to size 14), the minimal bodice support made the dresses seem more like the department-store-quality gowns the brides expected from the low price. The ball gown's pockets took it down a notch from formal — perfect for Michelle Garcia, 25, a bride whose expected dress budget is $500. But we had to replace the belt with a more elegant antique-style sash (Erickson Beamon belt, $978) to give the look some punch.

ann Taylor

We love that the retailer's three soft, romantic, no-fuss gowns are available up to size 18 and are priced under $500. Much like J. Crew's dresses, these gowns are lightweight, comfortable blank canvases that would work best for informal, casual weddings. So casual in fact, that it's easy to imagine Nicole Urso, our bohemian-inspired bride from Venice Beach, Calif., (who has budgeted $3,000 for her own dress) wearing a Silk Georgette Grecian Gown ($275) down the aisle and then out to her anniversary dinner the following year, the waiter none the wiser.
