Really who knows what minor Royals like Princess Alice look like?
I didn't think there was one any more?
Unless you're thinking of Princess Alice, Duchess of Gloucester, and she probably won't look very good on account of being dead since 2004 
@upinaballoon the current piper is Paul Burns who also piped for the late Queen. He's a serviceman attached to the Royal Regiment of Scotland, but I can't imagine he's doing much military serving between waking up Charles, escorting him to audiences, etc.
