Victoria Beckham: Philanthropic Mini-Me Dresses.

Victoria Beckham is just one of the designer names creating exclusive mother-and-child pieces for the charity Born Free. The designer unveiled a dress with a matching mini-me girls' counterpart - modelled by Vogue cover girl Sasha Pivovarova and her daughter Mia via Twitter.

Catwalk names including Alberta Ferretti, Alexander McQueen, Carolina Herrera, Celine, Chloe, DKNY, Diane von Furstenberg, Isabel Marant, J Crew, Marchesa, Marni, Prada, Rachel Roy, Stella McCartney, Tori Burch, Vera Wang and Versace will create pieces for the charity offering, to be sold on Shopbop.com.

Supermodel and philanthropist Gisele Bündchen will also create a design for the range, which comprises clothing and accessories for women and children. Models Karolina Kurkova and Doutzen Kroes have also been pictured with their children for the collection, which will be revealed in full next week and will be available to buy from April 23.

Born Free is a private-sector-led initiative with the ambitious goal of ending the transmission of HIV from mothers to their children by December 31, 2015. Beckham travelled to South Africa in February with Born Free to see the charity's work in person.

Kate Moss x Topshop.

Finally the lookbook of Kate Moss's Topshop collection is now available.

With everything from fringy jackets to slinky metallic dresses and even silk pajamas and a wedding dress, the collection is just like Kate herself: a little bit glamorous, a little bit boho, a little bit rocker and every bit amazing.

Organized into four themes, the collection features tailoring noir, balearic dressing, cocktail hour and pyjama dressing. What is exactly is tailoring noir? In a Moss world it includes slick suits, sultry smoking jackets, glitzy fringe dresses and liquid lame blouses. “I wanted to make the line chic and glamorous, while keeping the essence of the collection,” Moss says on Topshop.

"I have really missed being involved in the design process, and working with the team at Topshop," said Kate. "I am very excited to create a new collection that bears my name. Now more than ever, with London being at the forefront of fashion, as it feels like I'm back home working with Topshop."

The collection will be available online and in-store at Topshop, as well as Nordstrom, Nordstrom.com and Net-a-porter.com for the first time from April 30.

Kate Moss x Topshop.

Kate Moss talks about her upcoming collection with Topshop.

For her Harper's Bazaar magazine shoot, Kate wears pieces from her collection.

April 30th marks the day her collection will be available for purchase!

"Topshop.com just released a behind-the-scenes video featuring the designer herself, as well as a mood board (we spy that iconic yellow dress), and a collection of fabrics in bright pinks and metallic stars. But most importantly, we get to hear Moss speak—and considering that's not something the supe does very often in public, it's a real treat.

“I learned a lot the first time around,” she said. “This collection is a bit more sophisticated. Everything in the collection is something I’d definitely wear.”"

You can sign up to pre-order these 3 featured items on ShopBAZAAR starting April 15, before the entire collection hits on April 30. Reserve her black jacket featured above ($240), the silver sequin dress ($500) and the jumpsuit ($150) featured below—there will be limited quantities. Check back at Bazaar.com on April 9 for a full reveal of her fashion shoot and exclusive interview from the issue.
