Shopping for bras in Canada
Canada shops US sizing almost entirely, with the same DDD-style ladder and the same mall-brand fit habits. The wrinkle is cross-border online orders from UK and EU brands, which arrive with letters that diverge after D.
Knix, a Canadian native, sizes by its own 1-8 scale based on measurements; use your centimeter numbers with their chart rather than converting from a US size.
Brands you will commonly see: La Vie en Rose, Knix, Aerie, US mall brands.
