Most of the Royce bras fit on the snug side around the ribcage. We don't usually have to adjust your size from your regular size, however if you don't like too much firmness around the ribcage then I would recommend sizing up in the band size with Royce bras.
For example, if you don't like too much firmness around your ribcage and you usually wear a 10DD I would consider trying the Royce range in a 12D.
We always recommend reading the fitting notes that we write in the product description of each style, as not all bras from the same brand will fit the same.
