About the Cascadier Uniform Voucher
So that players can receive both body and leg gear, two Cascadier uniform vouchers will be distributed.
The vouchers can be exchanged for a Cascadier uniform by speaking with Aelina, who can be found in Mor Dhona at Revenant's Toll.

As much as I like adventuring into the great outdoors, going out of my way just for the bikini is a little too much for low level characters. I do hope they make it so we can redeem the voucher in starting cities.

After 30 days everyone should be able to travel there. Even new players need to wait until the 30 days free time is over before they can pay the first time and get the voucher.

Come on, don't say you don't enjoy this feeling:

In order to prevent gear damage, I recommend going at it naked.

Is the voucher set different from the wet bomb ash sets?

Haven't gotten my veteran rewards stuff yet and was just curious.

[Shirai]

No idea, even though I have visited the camp a few days ago (before billing) and registered myself tot that Aetheryte I have yet to return there to redeem the vouchers.

And yes, above picture is an accurate description of how I felt when I rode in there as level 23 character with all the imperials and Magiteks chasing me.

Yes, it's black, and the (female) bikini is a slightly different design that's about it. The design is slightly different than the striped suit, but the same as the other solid color suits.

FWIW, the short route I took was:
North Shroud: -> (Blessed Bud) -> Fallgourd Float > (Florentel's Spire) -> Coerthas Central Highlands -> Mor Dhona -> Revenant's Toll

Thirty days may be enough for most players. What about a new character being made after the thirty days? They have to wait for awhile or die trying to redeem a voucher?

WARNING: If you buy the wrong swimsuit set, you are out of luck as you cannot obtain the vouchers anymore. BE WARNED.
