Meaning what exactly? Costuming often evolves over the course of the season, and Satoko's and Kihira's programs were presented during exhibition in the month of May, so yes, the costuming can change by the start of the season and over the course of the season. But it's not a certainty that either Satoko or Kihira will be changing their costuming for competition.
I love a well-rocked bodysuit a la Vanessa James, and other ladies over the past few years. I don't have any problem with ladies wearing bodysuits. But I think much more exploration and experimentation should be done with costuming, particularly among the ladies. I'd love to see more ladies wearing pants (a la Maia Shibutani in the Shibs' hip hop SD), and not just skin-tight bodysuits.

Also, the music suits what she's wearing, IMO. In addition, Rachel Parsons wore kickin' pants and a top for her hip hop program with brother, Michael:

Part of the difficulty in experimenting with costumes is of course the requirement to keep costumes from interfering with the necessity to move expansively and to perform difficult athletic jumps, etc.
I think Satoko and Kihira look hot in what they are wearing. My main point is that I don't think their skin-tight black bodysuits particularly match the music they are skating to. Maybe if styled with a bit more color and imagination, the skin-tight feature could work a bit better. Or else pantaloons for Satoko along the lines of Oksana Baiul in
The Feeling Begins, but with less exposure on the top, and less bagginess in the pantaloons so as not to interefere with jumping rotation:

If Satoko prefers the skin-tight bodysuit, then why not make it with something more colorful and Egyptian-themed:

Or go with classic Greek-inspired dress styling, but not as long in length as this:

For me, Kihira's music brings something more fanciful to mind besides a skin-tight bodysuit, such as this:

Or maybe for Kihira (and I'm just talking about taking inspiration from these costumes, mind you):

The make-up certainly suits the fanciful nature of Kihira's music
