The reason the instructor is asking this young man to wear tight clothing is so he or she can see the true positioning of his body - ie. the arch of his back, angle of his ankle, positioning of his shoulders, etc. This can't be seen in his usual baggy clothing. I understand all the other dilemnas faced by male dancers when wearing tight fitting clothing but now is the time for this student to condition and acclimatize himself in all ways to the challenges of ballet attire. Good luck.[/i]
