Arizona is a very solid 5'10''. She has a very nice height, but she is far from being a member of the "giant squad".
I believe the tallest girls are Kirsi Phyronen and Irina Kulikova. I'd say they are about 1,85 (6'1''), or even a wee bit taller.
Karlie Kloss and Frida Gustavsson are around 1,84 (6'0,5''). Carla Gebhart and Dafne Cejas seems to stand at that height as well.
Julia Saner is very tall too, but I've never met her, so I can't be sure. Same with Magdalena Frackowiak.
Giant or not, this girls look fantastic on the runway. (except for Karlie, I don't like her
)
Not all the models are that tall though! In general, most girls are around 5'9'' to 5'11''. Freja's 5'10'' looks perfect for me. Nice and elegant still, but not so shocking.
On the shorter side there's girls like Hannah Holman, who I think is barely 5'7'', or even less, and Bambi who seems to be around that same height as well. Stunning anyways.
