Yes, I married Sylgia. I've done it before, my only other choices being Lydia and Ysolda. But I want to know if there is any way to change Sylgia out of her Miner's Clothes on the Xbox. According to the wiki, I can swap her pickaxe for a dagger, but I still would like her to at least look wealthier than our bard... Changing into clothes is preferable, but I'll take armor if I have to.

There is no way, but if you have 100 Pickpocket, and the "Perfect Touch" Perk, you can pickpocket her pickaxe, and give her any weapon you'd like her to have.
