I used Parisian on a label in Quark and used some bold and italic. Now, transferring to InDesign, of course you can't just bold or italic a font and I can't find a Parisian bold or italic to buy. Help.

There's a dropdown below the one for fonts that says 'Regular'. Click on it and other styling options should appear. You can find it on the Formatting toolbar at the top or on the little Character/Paragraph window:

I believe this is because you're using an opentype font, which doesn't allow for it to be modified within a program. You'd have to purchase individual licenses to each font weight.

I don't think Parisian even comes in a different weight or style than normal...
