So, I just found this today. Unfortunately, I don't have access to the Casino in anyway.
I found method to get those "clothes" in offline without Casino or the clothes from the Casino.
1. Unpack your game
2. Install latest
Unofficial Patch.
3. Do this:
3. Backup following files from
\Euro\Bnk\avatar\clothes\pnj:
- w_pn_d_dress_cardealer_hostess.bnk
- w_pn_d_dress_hostesslambo.bnk
- w_pn_d_dress_tess.bnk
5. Place
common_bodies.bnk in
\Euro\Bnk\avatar\clothes\pnj 3 times and rename as files you just backuped.
6. Start the game.
7. Go to Oahu island
8. Find the Pnj Shop
9. Apply the "clothes"
Hope it helps someone one day.
