...As much as Gregory & Petukhov improved this season (much better line and posture, greater speed, more difficult technique, a better relationship between the two, better edging and flow, better choreography...just everything was improved with the help of their new coaches)...as much as they improved, Gregory & Pethukov's unwise choice of costumes at Worlds probably resulted in a costume deduction that dropped them a place in the standings.
All season long they competed in beautiful costumes (the burgundy ones designed by Johnny Weir) that really accentuated and highlighted their improved line and posture, costumes that helped tell the story of their free-dance and then they show up at Worlds in horrible white leotards that hide their line and wash them out to the point that you could not even see their free-dance (against the backdrop of the white ice).
What were they thinking? If I were a judge, I would have dropped them a place too.
