It hasn't been seen since last July, so it's been out for over a year by this point.

I don't know if there's going to be another TG/DB event. The event schedule seems pretty tight, but I think there was a datamined image for the event in the latest set.

Hopefully we see it though. I'm kinda annoyed with certain things, especially hairstyles, just being unavailable for so long.

As for houses, I think they sometimes run an ESO+ discount, but that's usually for the ones you can only get from the store and usually for the ones that match some theme they're going for. I don't think it's common though.

Yeah, there's a thread about all of those around here:

We haven't heard anything from ZOS, but there was an interview suggesting that future hairstyles would be available for both genders... if they ever put more hairstyles up...

Several of those need to release - especially since things like Unruly Bangs have a dyed equivalent that was made available (Magenta Rainbow hair from the Dwarven crates). And the fact that styles like Short Mussed Wave have been featured on a bunch of the nameless festival NPCs in addition to almost every other piece of promo art lately.

I really want Short Mussed Wave...

Even styles like Adorable Assassin and Heroic Poet were available, but haven't been seen in ages. I've been around for a year, and I haven't gotten either. And again, you see some older players and loads of NPCs with them. I've even noticed the new DLC NPCs are much more likely to wear these hairstyles that should be available.

At least one from that list has been datamined and named: The werewolf mullet "Misanthropic Lycanthrope." Hopefully that's inbound, but we know that things like Short Mussed Wave hand Unruly Bangs were even on PTS but never made it live.

If anyone from ZOS is reading this: Please give us these styles! I notice that we're getting close to the August showcase, and you'd get loads of crown sales if you put up a Crown Store pack of Short Mussed Wave/Unruly Bangs/etc.
