We were given the task of creating a diffusion range for our designer, and to be honest I had heard of the concept but I wasn't clear as to what a diffusion range offered, so I began my research online... "A diffusion fashion line is the name for an accessible ready-to-wear line for the masses produced by a major designer who usual sells expensive couture. It all started when designers began creating diffusion lines of their own labels like D&G by Dolce & Gabbana and Gianni Versace’s Versace Jeans Couture. In the past few years, the new trend is for designers to create fashion lines for discount chains and department stores such as Vera Wang’s Simply Vera line for Kohl’s." You can read the whole article by Marsha West here. So it got me thinking about the pros and cons of diffusion ranges in terms of: style, price, fabrics, customer outlets etc before I design my own. Here are some examples that relate to my designer, La petite Salope. I chose these designers because I like the way these ranges are not too watered down in terms of design keeping a real essence of the designer, which is what I want to create in my own range. The Square Dress from Vivienne Westwood’s Anglomania label. 'The draped tailoring is stunning and very reminiscent of the gorgeous Vivienne Westwood navy pin strip suit that Carrie wore in Sex and The City to her lunch with boss at Vogue. Perfect for day or night this is a great one piece for work. Features include a detachable self tie waist belt, buttons to fasten the neck and a cowl neckline. Available for £270 from Net-a-Porter. The pieces for this range are designed for everyday wear and are great for adding a bit of her iconic style to your closet at a more realistic price. T by Alexander WangThis diffusion range consists of cotton basics in 12 styles. Wang launched an online lookbook of the collection ranging from tanks ($28 wholesale) to T-shirt dresses ($40) — all cut in the designer’s signature languid style, with colors ranging from simple whites and heather grays to lavender, chartreuse and cerulean. “Necklines are stretched and armholes are strategically lowered so that it looks worn in,” he explains. “It’s like sleeping in a T-shirt and then wearing it the next day. It’s not this crisp little T out of the dryer. It’s draped and kind of wilted.” Jean Charles de Castelbajac (JCDC) The first JCDC collection is called Punkahontas and the Ducks. Jean Charles de Castelbajac JCDC range is made up of shirts, skirts and jackets. Starting from around $85 for a t-shirt. Rachel Roy debuts in Macy's Rachel Roy's diffusion line is available in over 80 Macy's stores. The collection includes sportswear, footwear and accessories. Some items in the collection feature bright patterns and unique prints including a graffiti print that is featured on apparel, shoes and handbags. Items in the line retail from $59 to $299 for sportswear, $79 to $199 for footwear, $40 to $195 for jewelry and $69 to $109 for handbags. "I'm always inspired by women I meet - how they dress, how they put outfits together," said Rachel Roy. "The art of fashion and seeing it come to life through personal expression and interpretation is a huge catalyst for me. Accessible fashion has always been a passion of mine and was a priority consideration in creating the Rachel Rachel Roy collection for Macy's. I chose to design the collection for the younger sister of Rachel Roy."
