I'm pretty sure that previous event only automatically gave you the set for your gender and you had to earn the other, and in any case I think you can now buy it from the Calamity Salvager (or the other one that deals with seasonal gear).

Also worth noting that the coffers are labelled "vested" and "frilled" rather than by gender, in line with the recent renaming of the old sets. I think all signs point to it being a future unlock, even though it does seem an odd order to tackle it in.
