The cup on the Delirious Soft Bralet is on the smaller side and we recommend this soft style bralet for an A cup. You might have been more comfortable in a M/L than S/M since the band is a touch wider. If you are looking for a 36A/B.
I would also highly recommend the Pima Plunge Bralet as an alternative option.
