HerRoom Response: Appreciate your feedback, but we have no sizing advice telling your to change your usual size.
Pure Lime Response:If you wear a 32C in her everyday bras, the chart says you should buy a 32C Pure Lime bra. If you bought a 34B, it should still fit in the cups. I can't answer why the bra didn't fit unless it was tagged wrong.
