We were shocked to hear that one of the first (and few) celebrity lines to succeed, Twenty8Twelve, announced today that notoriously stylish Sienna Miller and her designer sister Savannah Miller have left the label. Come fall, the label will change its name from Twenty8Twelve by s. miller to Twenty8Twelve London. Despite the loss of the two co-creative directors, the brand will still show at the upcoming London fashion week, and has plans to expand into e-commerce and open a new store in New York (in addition to their successful London stores and sales in department stores worldwide).

This news about one of the most prominent celebrity lines got us thinking about celebrity status and fashion-line success. We revisit 10 of the best and worst celebrity fashion lines out there and give you our verdicts.

We count ’em in no particular order »

BEST: The Row

Mary-Kate and Ashley Olsen’s line of luxury basics, The Row, was inspired by the quest for the perfect T-shirt. The sisters have been quite clear that they are involved in every stage of design and production. And, if it’s any indication of its success, the collections are sold in Barneys and Holt Renfrew shoulder to shoulder with Dolce & Gabbana and Marc Jacobs. Having just hired Prada’s former CEO to head up operations, we daresay the future’s only getting brighter from here.

WORST: The Lauren Conrad Collection

The super-simple jersey basics of Lauren Conrad’s eponymous clothing line were overpriced and hard to sell.

BEST: L.A.M.B

Selling over $90 million dollars of merchandise in 2007, Gwen Stefani’s L.A.M.B. is a total success. The clothes are a mix of high fashion elements and the rocker’s own ska-punk style, and are consistently well received by fashion critics and celebrities alike. It probably helps that Stefani name-drops her line in her music too.

WORST: JWoww

The reality star’s label, Filthy Couture (yeah, we’re not kidding), shut down after just five months because of a conflict over the rights to the name. We’re not sure why anyone would fight for that name, but we thank them for protecting us from the line of barely-there dresses.

BEST: Kate Moss for Topshop

The supermodel designed 14 collections for the retailer over three years to rave reviews. The collection spurred a cat fight (over a £100 leather dress, no less) and routinely sold out to frustrated consumers, once in less than 15 minutes. The collection was so successful because it was representative of the model’s own killer London style.

WORST: Lindsay Lohan at Ungaro

Perhaps the most laughable foray into fashion was Lindsay Lohan’s ultra-brief stint as artistic advisor at Ungaro. The rhinestone-laden collection (complete with nipple pasties!) was deemed a total fashion embarrassment by WWD and just about every other fashion voice out there.

BEST: Victoria Beckham

Victoria Beckham’s self-titled clothing line of fitted, well-constructed dresses, handbags, and separates is a red carpet favourite. In fact, the line won Designer Brand of the Year award at the British Fashion Awards (yes, that’s right she beat Stella McCartney and Tom Ford). The ex–Spice Girl’s line was estimated to have brought in 60 million pounds by the end of 2011.

WORST: Heidi Montag’s Heidiwood

Heidiwood, Heidi Montag’s fashion line (if you can call it that) was dropped by U.S. retailer Anchor Blue just one year after its conception. The line of cheap-looking zebra-print halter tops and micro-micro-micro-shorts failed to garner a following.

BEST: Jessica Simpson

Jessica Simpson’s collection of footwear, accessories, and clothing reportedly earned her $1 billion in sales in 2011 (a record for celebrity fashion lines!). The odds seemed somewhat against her, considering her failed music/acting/reality TV career, but the combination of an affordable price point with tasteful and simple designs has proven to be an attractive one for consumers.

WORST: Holmes & Yang

A partnership between Katie Holmes and Jeanne Yang, Holmes & Yang has been a bit of a commercial flop. Critics have said her clothes are unflattering, busy, and too expensive.
