Cross-border sizing in four steps

  1. Keep your Canadian size Your CA size is already usable in the United States.
  2. Check size guides Canadian sites often list US/CA along with EU or FR references—confirm you’re reading the correct column.
  3. Use sister sizes for comfort Band adjustments work exactly the same on both sides of the border.
  4. Review brand fit Focus on brand-specific notes—materials and cuts influence fit more than the size chart.

Canada to US conversion FAQ

Do I need to convert Canadian bra sizes to shop in the US?

No conversion is required—Canadian labels use the same inch-based bands and cup letters as US sizing.

Why do Canadian tags show both languages?

Brands print English and French on the care label, but the size column stays in familiar US-style notation.

What if a Canadian brand lists EU or FR columns too?

Use the US/CA column first. Secondary EU/FR columns are there for international shoppers but don’t replace the main size.

Which US sites ship to Canada with these sizes?

Retailers such as Bare Necessities, Nordstrom, and Amazon US ship to Canada while honouring the same size grid.
