They decided against showing the ladies topless during the awakening?
I'm guessing so.
Both Veronica and Sigourney were topless in the behind the scenes photographs of the opening (save for a thin white band covering going around their chest for the sake of covering their nipples).
No need for them to be topless unless they were originally going to showcase them? They didn't take their tops off for a laugh! Though as all who have seen this film will know that there is a conspicuous lack of both ladies during the awakening segment.
I'm guessing they balked at it at some point?
The images; (NSFW I guess but not much is shown really.)
