I agree with Deblas. If you look back ( Arlong arc), Nami is typical 5 foot 10 inch girl. During Water 7 acr she seems taller. Either that or they are making parts of her body out of proportion. It could be that camera focus on her is either too close and they want to show her larger than life during this emotional part of the story. She seems almost as tall as Robin in the last episode.
Ever since Water7 began, Oda has been drawing Nami with more leg. Add to that the long skinny waist she has and you have a giant.

And Nami isn't 5'10. A 5'10 is considered pretty tall for a woman actually. She's approximateldy 5'5 inches tall. [img]i/expressions/face-icon-small-tongue.gif[/img]

These are the strawhats heights that Oda has confirmed:

Robin- 188 cm
Zoro-178 cm
Sanji- 177 cm
Usopp- 174cm
Luffy-172 cm
Nami- 169 cm

Approximately rounded up to the nearest half inch they would be(the conversion was done by someone in the Arlong Park forums):

Robin- 6'1"
Zoro- 5'8"
Sanji- 5'7"
Usopp- 5'6.5"
Luffy- 5'6"
Nami- 5'5"
