I know about sister sizes, I have a 32C that I wear when laundry day hasn't happened and a sports bra isn't appropriate. It doesn't fit, I hate wearing it and its not really comfortable.
Does anyone know how accurate LaSenza sizes are? I typically shop online, I live far from any city. The busy season just started so I likely won't get near a city for another 3-4 months. Any help? I'd like to avoid having to do a bunch of returns. My measurements did result in me needing a 30D last time I checked so I'm reasonably sure that's the size I need.
