The PlayStation 4 version of Ys VIII: Lacrimosa of Dana only had a few DLC costumes, which included the Silver Armour for Adol, the Eternian Scholar for Laxia, and the optional colour changes that Alison would prepare for the characters at a certain chapter in the game. The costumes themselves are references. Adol's Silver Armour is a reference to the default look he has had, most notably in the first and second Ys games and Ys: The Oath in Felghana, while Laxia's Eternian Scholar is directly based on the Eternians from Ys VIII itself.

For the Nintendo Switch port, more costumes were added for the 6 playable characters. All characters received the "Deserted Pirate" costumes, which follow on the theme of Pirates that were often mentioned up until the fight against Captain Reed in Ys VIII, while Adol, Laxia, Ricotta and Dana all receive "Tropical Swimwear" attire, which gives them swimsuits of various designs.
