SB 9.1.30
tan vilokyambika devi
vivasa vridita bhrsam
bhartur ankat samutthaya
nivim asv atha paryadhat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When the goddess Ambika saw the great saintly persons, she was very much ashamed because at that time she was naked. She immediately got up from the lap of her husband and tried to cover her breast.
