Update 7 went live on Bullroarer yesterday and as usual I had to take a look and see if anything cosmetically interesting is happening for Update 7. The good news is: YES THERE IS!!
I guess the best cosmetic news for myself (and I believe many others) is that all raid gear from the Rift will be available at the Cosmetics vendor. Just like the Annuminas and the Helegrod sets, they will cost 547 marks and 33 medals per piece. However a slight change is coming to these raid cosmetics: as of Update 7 they will be Bound to Account. This is valid for all Annuminas, Helegrod and Rift pieces, so you won’t be able to pass them on to someone else anymore. The regular cosmetics remain Bind on Equip.
The Classic vendor will have all the old gear drops from Fornost available as regular armour. These items are mainly old world designs.
A completely new cosmetic item has been added to the Skirmish Cosmetics vendor: the Hauberk of Mystery boxes. There are three different boxes and they cost 63 marks each.
SPOILERS AHEAD, do not read if you want to find out how it works by yourself!
I purchased one of each box and found three pretty hauberks with a blank yellowish front inside. I couldn’t really find anything particularly mysterious about these hauberks at first, other than their new design. It wasn’t until I activated the dye options in the dressing room that I noticed that a pattern is revealed when using dye! I purchased another set of boxes and lo and behold, they revealed a different pattern upon upon dyeing! It looks like these patterns just appear randomly. I do not know how many different kinds of patterns* are available, but chances are that you end up with a completely unique hauberk! I think these items are a very nice addition to the existing hauberks collection.
*Edit to add: Jonathan Andrist was kind enough to sort out the variantions and found 20 different possible patterns (see his comment below).
Padded Hauberk of Mystery
Leather Hauberk of Mystery
Chain Hauberk of Mystery
Unfortunately the Lotro Store is not available right now so I cannot check if anything new has been added there. I will update this post if I find out.
