I have to agree with Zhavi on this one, while I personally think it would be awesome to use the female model for more feminine kitty boys, the only robe I've noticed that actually makes it possible for that model to look androgynous is the that one alone. The rest of the robs, as Zhavi stated, tuck in at the waist for curves and almost clearly define the chest no matter how small it is. Now you could always of course put in his tag that he's supposed to be male but that's completely up to you, somehow I doubt you'll have many problems from people OOCly for it.
So in other words, for simplicities sake you could go with the male model, but on the other hand if you like the female model best and don't mind doing some OOC or IC hinting at his gender I say go for the female model! My roommate (who unfortunately is rarely on) is using a female model for her very feminine male character and I think it looks good when it comes to the face. Though the animations are admittedly hard to pass as anything male.
