I think Vienna's hair and makeup were done by a stylist. Maybe she spent the day at a salon, knowing Ali was on an all-day date with Jake. And she's wearing a fancy necklace. Seems like she decided to go all out.
Also, the fancy nails might be hers as well. I didn't think so before because her nails just the day before were so short, but she wears a similar ring on the middle finger of her left hand. So maybe she also had fake nails put on at the salon.
