Do you mean, would you dress differently if the deceased were a young person than if the deceased had been elderly? No. At a funeral, you're dressing more to respect the family and the setting, unless the family has requested something to honor the deceased. At a casual funeral in the US, for example, a family might request people wear the deceased's favorite color.
But since you're dealing with traditional family members who live in a different country from yours, dress with respect in a subdued way. (And since you will be at the cemetery in a village, no high heels that are going to get caught and ruined in grass and gravel.)
