"She may not remember me, but I remember her....."

Raoul wears this costume in his first appearance as young Raoul - seated in the managers' box during "Think of Me". He wears a proper tailcoat with white waistcoat and a white shirt. The white, delicate ruffled shirt appears to have proper studs in front, but as for the Phantom's costume I suspect most versions have snap buttons underneath. The shirt has a turndown collar, and he also wears a white bowtie and white gloves. Originally the tailcoat had a white carnation on the left side, but this is cut in most productions. It does appear in the US every now and then, though, and I think it's a nice touch.
