After reaching out to Daum about the costume prices in the Black Desert Online shop, the team has responded. Overall costume prices will be reduced ~10% from $32 to $29. Costume sales will continue at official launch with the development team keeping a close eye on community reaction and will assess feedback received. Adjustments will be made as necessary.
Note, this price is the total price of a full costume and weapon skin. Costumes alone will still be around $20.
EDIT: Updated wording to note that the shop is closed during Head Start, as well as that the $29 price is for costumes+weapons.
