Solange Mangano's buttocks surgery was stupid for a woman who had everything in its place, designer Roberto Piazza told Argentinean media.

Mangano, 38, a supermodel crowned Miss Argentina in 1994, died of a pulmonary embolism Sunday after the liquid used in the gluteoplasty went to her lungs and to her brain, the Associated Press reported. The gluteoplasty is a procedure which usually involves placing implants in the buttocks.

She took care of herself a lot. She went to the gym, had everything in its place, perfect measurements, a divine waist, Piazza said, according to La Nacion newspaper.

Last year she had surgery on her breasts and they came out perfectly, but she didn't need this buttocks surgery. What she did was stupid, I can't understand it, he added, according to the paper.

Mangano is survived by her 7-year-old twins and husband.

Argentina is the No. 8 country with highest plastic surgery procedures in a list topped by the United States, Mexico and Brazil, according to the International Society of Aesthetic Plastic Surgery.
