Oh, you meant for your playthrough? Right, right... are there any images of their alternate costumes floating around? If that's a dealbreaker for you, decide based on that. Pretty sure customization is on a middle-ground between XY/SM/USUM/SwSh and LGPE.
>skin tones at start of game>alt costumes and headgear similar to LGPE, but diversified further than Chase and Elaine's palette/texture swaps>lacks the full range of options found within the other games, such as hairstyles, contact lens, and other piecesThis is all to my knowledge, at least. Someone who has already delved into BDSP may be able to give you more information on Lucas and Dawn's customization options in those games.
