Gurl, did you know?

  1. Bra sizes are not standardized across brands, so the size you wear in another brand may not match up to your La Senza size.
  2. Bra fits should be done at least every 6 months to ensure you have the right size.
  3. The right fitting bra can enhance your silhouette and help your clothes fit better - instant boost!
