Why do people consider Gisele Bunchine curvy?

Why do people consider ex-victoria secretet model gisele curvy? I don't understand because every time on vh1 and those types of channels they always say "She has so much curves!" and all I see is a ruler shaped, boyish body that's tall. I thought curves were like pear, hourgl shaped. Like marylin monroe,halley barry, scarlet johanson or beyonc'e. I know some thin people have curvse but with her all I see is a straight body. So can someone please explain to me what their seeing because I'm honestly confused? I wonder if I'm blind. I love Gisele but are they saying straight & skinny is curvy and curvy is fat?
