Singer-actress Jennifer Hudson is launching her own fashion line.

Hudson, who won an Oscar for her role in Dreamgirls and is a spokeswoman for WeightWatchers in the United States, is teaming up with bosses at television shopping channel QVC to release an affordable clothing collection for women with curves.

The range will be designed for females between US sizes 6 and 16 (Australian sizes 10-20).

"I feel like I represent every woman," Hudson told Women's Wear Daily.

"I've been on both sides of the fence. I've been a big girl and now whatever this is, the average size, whatever you want to call it.

"But I wanted the clothes to be where any girl could wear it - no matter what size you are - and you could feel comfortable in it."
