Shopping for bras in Australia

Australia numbers bands by dress-size logic: an AU 10 band equals a US 32, AU 12 a US 34, and so on. Cups mostly follow the UK ladder, so an AU 12DD is close to a UK 34DD. Confusion arrives with US imports whose DDD does not exist locally.

Aussie brands like Berlei and Bonds fit warm-climate priorities: breathable fabrics, wirefree engineering and strong sports bra ranges tested for impact.

Brands you will commonly see: Berlei, Bonds, Bras N Things, Lovable.
