Need help deciding on Rolex size for female

[Lana106]

Hi,
I'm new to the forum. I'm looking to purchase my first rolex and before I can even think of the watch I want, I need to pick a size.
Will the 26 always be in style? I have a tiny wrist but do like the way some of the mens watches look and someone said resale value is always better on the larger sizes,although if probably keep the watch forever.
Any help would be appreciated.
