Matrix is right. Giselle's skills are so trivial as to be depressingly commonplace.
Body88 is confusing who, exactly, has the skill here. THE CORPORATIONS HAVE THE SKILL. Giselle has become as irreplaceable as any top pitcher, doctor, scientist, etc. but not by her own skill, but by the cunning and craftiness of the companies she works for.
They chose her, who the hell knows why, right place right time, undoubtedly. Then they paid her shitloads of cash FOR THE EXACT REASON THAT SHE WOULD APPEAR INVALUABLE. She is not giving them a "return on investment" LMAO!!! The headline "GISELLE BUNDCHEN PAID 25 MILLION A YEAR" is giving them their precious ROI... THE HEADLINE.
Matrix is right -- fashion is an industry inherently devoid of skill, use-value, etc. It is a world of sign-value -- of appearances. Giselle has no skill of her own, could be any one of a hundred-thousand similar girls, but she won the lottery and then the fashion companies went hard to work using THEIR skills to TRICK everyone into thinking that she was so great, so that, in return, the could continue to fool people into thinking the clothes she wears are great.
