Vaishnava Samhita. Shri Vyasadasa Charitam I. Vol II Book VI Chp 2 Shlokas 19 - 20

करं गृहीत्वा कृष्णस्य वृषभानुसुता च सा 
नित्यं षोडशवर्षीय नानाभावप्रदर्शिनी    ||

श्वेतचम्पकवर्णाभा जगन्मोहनमोहिनी
ननर्त पुलिने रम्ये क्वणत्कनकनूपुरा   ||

Shri Radha the beloved daughter of Vrishabhanu ever dazzling young, as lustrous as the champaka flower, an adept in displaying different expressions during the dance, wearing tinkling golden anklets, exceedingly beautiful as the bewitch Shri Krishna Himself and capable of enchanting the entire universe, danced merrily on the silver sands of Yamuna, holding Shri Krishna's hands.
