I can imagine someone telling Bulma she's "spoiling" him by holding him all the time and she'd tell them to fuck off he's her baby and she'll spoil him if she wants too.
Not only is he dressed nice but he's at an event for Bulma he couldn't be bothered to go to her birthday till she forced him earlier in the season, that's how much he's grown and changed not just in Z but through Super too.
