ترجمة - انجليزي-إسبانيّ - Would you like to customize José's appearance?...

José is the main character of the game. I would like to offer players to customize his appearance by dressing him up with many accessories.

O bien, más simple y escuetamente: "¿Quieres personalizar la apariencia de José?".

("Aspecto" would be also OK instead of "apariencia".)
