Leigh Viner is a breath of fresh air for fashion illustration - she presents an enticing fantasy-world of beauty, but still allows "imperfections" like loose line work or pain splashes give life to her drawings.

She has an etsy store here:
Her website of work is here:
And she shares her inspirations on her blog here:
