Kelly Osbourne is launching her own fashion line, which will be available in sizes 0-24 (US sizing).
I believe it will be sold via an online shopping network in US, so I'm not sure we'll have immediate access to it here in the UK.
What is interesting about the Kelly's range is that it will be available across the size range, from size zero to size 24 (in UK sizes I believe that is a 4-28). I'm not aware of many of collections that span that wide of a range. The plus sized ranges usually start at 12/14 upwards, so the idea of a truly inclusive brand is pretty exciting.
