Just something to toss in here, had to give them proper pics after talking about them with
The idea behind their younger physical appearances is that Reshirams and Zekroms age much slower than most other species that enter the "golden years". So yeah, that explains the lack of wrinkles and hunched bodies :P
Sera's parents can technically be put in the higher social class-they have made quite a fortune over the years (probably enough to even secure the future of their potential grandchildren :P)
Alphonse Divano (age 73)

Alphonse is known as one of the most respected and loved professors at the prestigious private college in Castelia City, reserved for the elite of the Unova's society. Unlike most of his colleagues, who come off as cold, stuck up and distant drones, Alphonse has always been treating his students more like friends, making sure to help them not only regarding the school matters, but personal ones as well. Students grew fond of him and began to see him as a sort of father figure. Wise, calm, kind and relaxed all the time, he never cared much about fancy parties, hanging out with the social elite, or some sorts of dressing codes. He lived the life as he saw it fit.
When Seraphine graduated, Alphonse offered her a financial support and to pull some strings in order to help her find a job, however he was caught dumbstruck when she refused it, deciding to make a path in life on her own. This fact alone made him proud of her, and he supported her at every step-except when she informed him and her mother that she began working as exotic dancer. At first equally disapproving of such choice like his wife, Alphonse soon gave up on trying to make Sera change her mind, remembering when she said she's making her own choices, and after realizing that majority of stereotypes that followed her type of work weren't true. He's still somewhat uneasy about the fact, but he supports her nonetheless.

Celeste Aurelli Divano (age 71)

No-nonsense owner of a successful record company specialising in classical, symphonic, sung poetry and generaly refined music, Celeste is known as a sophisticated, elegant and well-mannered lady-strict, pedant and professional in every sense. She took it upon herself to make sure her family is taught about manners and what means to be a part of the social elite. She's a bit of an opposite of her husband behavior wise, but despite their differences she loves him, and so far the two pulled off through the 50 years of their marriage-she actually mellows down a bit when she's alone with Alphonse. Despite her thirst for perfection and professionalism, she's not too demanding-she knows everyone has their limits, including her beloved daughter, Seraphine. After hearing about where her daughter works, she did all she could to talk her out of it, but has failed. She still can't get over that and will often carefully bring up the subject during the conversation with her.
