This past Sunday was Super Bowl Sunday in the US (2/12/2023).
I watched the Half Time Show. Every year, they employ hitmaker(s) with long career and it is solid entertainment. This year, it was by Rihanna.
One noticeable visual was, everyone was wearing "fat suits" (ehm, "oversized/baggy" suits or "bubble/puffer" suits) in red (Rihanna herself) or white (all other dancers).
The suits might have been for covering up and not to draw attention to the body line, I thought. Indeed, it turned out later, that the lead Rihanna was pregnant. Hers was maternity suits and everyone else was wearing the suits to match hers.
And it is perfectly legit in show business. You can choose costume that only show what you'd like to show.
There are layers of things dancers can work on for their appearance.
In the order of difficulty and efforts, they would be;
Level 0. Filming and complimentary editing
Level 1. Dress, Costume, Accessory
Level 2. Hairdo. Makeup.
Level 3. Body management (diet, gym work)
Level 4. Posture work. Dance motion cleanup (drills), Flexibility training
Level 5. Use of good Choreography
Level 6. Work on Stage Presence
Yes. Managing costume is level 1. Not difficult. Smart move, producers and performers.
