I try to go see an many companies as I can but when I am unable to go I try to keep up to date through magazines and websites like ballet talk.
As for the most beautiful dancers I think the some of the current ones that come to mind to me are
Saskia Beskow (NYCB)
Kristin Sloan (NYCB)
Julie Kent (ABT)
Julie Dianna (PAB)
Barette Vance (PAB)
Amanda Schull (SFB)
Maria Chapman (PNB)
Karine Seneca (BB)
