After a longish break i noticed that a riding hat has been added to the venia outfit but am not sure how to get them to update the the outfits I previously purchased.  Anyone know how?  i dont see them in the pearl shop and hopefully i wont have to spend additional cash to update the 3 or 4 outfits i own.

It's there under the Venia outfit listing.

It was added as an additional item to purchase, so if you want to add it to the outfit you currently have, you sadly will have to pay
