how is the scarlet letter designed

Here is a quote from the book:

On the breast of her gown, in fine red cloth surrounded with an elaborate embroidery and fantastic flourishes of gold thread, appeared the letter 'A.' It was so artistically done, and with so much fertility and gorgeous luxuriance of fancy, that it had all the effect of a last and fitting decoration to the apparel which she wore; and which was of a splendor in accordance with the taste of the age, but greatly beyond what was allowed by the sumptuary regulations of the colony.
