In July 2008, Lavigne launched the clothing line Abbey Dawn, featuring a back-to-school collection.[12] It is produced 由 Kohl's, which is the brand's exclusive U.S. retailer. Named after Lavigne's childhood nickname, Abbey Dawn is designed 由 Lavigne herself.[101][102] Kohl's describes Abbey Dawn as a "juniors lifestyle brand",[12] which incorporates skull, zebra, and 星, 星级 patterns, purples and "hot pinks and blacks". Lavigne, who wore some of the clothes and jewellery from her line at various concerts before its official launch, pointed out that she was not merely licensing her name to the collection. "I actually am the designer. What's really important to me is that everything fits well and is well-made, so I try everything on and approve it all."[103]
“    I just 爱情 clothes and 颜色 and patterns. I'm very visual and very hands-on.    ”
—Avril Lavigne, Billboard[104]
The designs were also featured on the Internet game Stardoll, where figures can be dressed up as Avril Lavigne.[105] On 14 September 2009, Lavigne took her latest collection for her clothing line to be a part of the New York Fashion Week.[106] "It's fun to be a chick and 设计 clothes and things I'd like for myself. I 设计 things I [can't] find."[62] In December 2010, the clothing line was made available to over 50 countries via the line's official website.[107][79] At the end of 2008, Lavigne signed a contract with Canon Canada to appear in ad campaigns and commercials to promote the latest line of cameras, along with a full range of other accessories.[108]
Lavigne released her first fragrance, Black Star, created 由 Procter & Gamble Prestige Products. The fragrance was announced via Lavigne's official website on 7 March 2009. Black Star, which features notes of 粉, 粉色 hibiscus, black 李子, 梅花 and dark chocolate, was released in summer 2009 in Europe, and later in the U.S. and Canada.[109] When asked what the name meant, Lavigne replied, "I wanted [the bottle] to be a star, and my 颜色 are 粉, 粉色 and black, and Black 星, 星级 resembles being different, and standing out in the crowd, and reaching for the stars; the whole message is just about following your dreams, and it's okay to be unique and be who 你 are."[110] Black 星, 星级 won the 2010 Best "Women's Scent Mass" 由 Cosmetic Executive Women (CEW).[111] Black 星, 星级 was followed 由 a 秒 fragrance in July 2010,[112] Forbidden Rose, which took two years to develop.[113] It features notes of red apple, winepeach, black pepper, lotusflower, heliotrope, shellflower, praline agreement, sandalwood, and vanilla.[112] Its message is an extension of Black Star's "follow your dreams",[114] though the tagline for the new perfume is "Dare to Discover".[115] The commercial takes place in a 哥特式 garden setting,[114] where Lavigne, upon entering the garden, finds a single, purple rose.[115] Lavigne is to launch a third fragrance in August 2011 and filmed the commercial for it in late 2010.[79]
