The owner of lingerie chain Bras 'n' Things, Brazin Ltd, on Thursday posted a huge jump in full-year net profit and said it expects strong trading to continue until at least the end of the year.

The Melbourne-based company, which also owns the Sanity Music store chain, said its net profit more than doubled to A$23.3 million from $11.3m in 2001, with group sales up 25 per cent to A$489m.

It added the 128-strong Bras 'n' Things chain had got off to a solid start in the new fiscal year after strong second half sales and said it plans to open six new stores before Christmas.
