Gabriel, i agree Isabeli is chameleon and Riccardo loves her, i was sure she was called for the campaign after a lot of seasons walking for him, this time she was invited in first row. the problem i think it's more with M&M, they never worked with Isabeli (maybe once in 15 years of isabeli's career, so it must be that they don't really like her)...
anyway in that interview there is a good (old) story of Isabeli talking of this usual problem she had/has, but thanks god that time went differently: clients refused her because they were looking for something less sexy and the biggest casting director Maida Grégory Boina wasn't interested on Isabeli's beauty at all, because she liked more other genres of girls. But Isabeli insisted to show her a new walk, less sexy and more androginous, and then she was booked for Balenciaga show and campaign
so, for Givenchy, it's their loss
anyway dear, with Isabeli i talked in english and italian

she was a dream and very available for fans

i think you can have some more chances to meet her if you go to SPFW or RFW..
