Well, to get scuba it requires a lot of time, effort, and money as it is one of the rarest pieces of DKNY on stardoll, being the first season and everything. Considerably, it is probably easier to get than LE, but of course still a complete challenge. To get it, this is what you need to do.
1. You must be superstar.
2. Check rare collectors. Often, many rare collectors such as xLou26, MissLolita_F, saphiredakota2, and many more are often getting rid of their stock.
3. Have lots of money. Some will ask you to pay high amounts of stardollars, while others may ask for real money, transferred over PayPal, or sometimes even stardoll upgrade codes.
Good luck! xx
