Fit for a Jarl

Walkthrough
In Solitude, the Dragonborn can speak with Taarie, the owner of Radiant Raiment. She is always quick to disparage whatever the Dragonborn may be wearing but does offer a more stylish outfit.

Additionally, she offers to give the clothes to the Dragonborn for free if these are worn in front of Jarl Elisif the Fair and the her shop is plugged while at the Blue Palace.

Speak to Elisif with Taarie's outfit on
So when wearing the outfit a dialogue option will become available, letting the Dragonborn ask how the Jarl likes the outfit. She will be delighted, promising to order several outfits from Radiant Raiment.

Tell Taarie what Elisif said about the outfit
Return to Taarie to give her the good news.
