I think what you mean now, it's however a question of preference. Her clothes actually don't change during the event. (I don't see any code that changes her actually outfit or I'm blind)Here's a little anomaly, not a major thing. Early on the game (yes, I started again...) May gets automatically moved to the bathroom for a shower and we encounter her mother, half naked for the first time. When the encounter is over, we can't have that shower because, although May's icon is showing her wearing her towel, the game thinks she isn't, so we have to go all the way back to the bedroom, change into the towel then go all the way back to the bathroom again for the shower.
So she should still be in same clothes after the event. So yes if you want to have a shower (It's not needed or since only the first day it's mandatory so why would you bother? I know It makes "no sense" from a role playing perspective.
On the other side if I change it so she would be in her towel. The players that don't want (waste time) to take a shower will have to run back to her room to change back into her regular clothes again. I suspect, but maybe I'm wrong, that the choice the majority of the players will make. I just made a small change that puts her back into her room after the event, since that's kinda the "middle" ground.
