Freya Response: Certain frames will fit differently depending on style and fabrication, so don’t be alarmed if you find you wear a certain size in one style, and a different size in another. It’s important to be flexible about your size. AS3423 is a padded sweetheart style which often fits a bit smaller than some of our balcony styles. The good news is we have so many cup sizes to choose from, so it’s easy to go up or down as much as you need for your perfect fit! Michelle from las vegas, nevada, usa
