Given that life skills cap has been lifted, I would be shocked if new tailoring and blacksmithing patterns weren't added. That's probably what they're talking about.
Though if you do find any new ready-made clothes, be sure to mention them here so the rest of us can find them please.
What's shown in the ads, and the video (made by Nexon in Korea, and merely regionalized for us) do not reflect what Nexon America will be implementing.
Ailionoa sells two new (cheap-ish) clothes. One for girls, one for guys. Both "great for Production masters" or something like that in the description, and the girls' one is more expensive than the guys'. XD
