Late to this thread since I don't hit the women's forum very often.
Kiwami might fit in the smallest size, It's pretty stretchy though. But Andre might be able to adjust the length of the arm sleeves a bit. I've got 1-2 females racing in these so far with good results.
Cuore which my partner Heath (ex-cyclist on ST) helped design now does some different lengths for arms and legs. I've got several petite female athletes (say 5-4 and under) racing in their suits and they love them. IMO probably the best option out there for women currently
One other option to consider is Scody. They make some women's specific suits as well. We've done some wind tunnel work for them a few years ago. I've got 1 athlete racing in this and she likes the fit. She's a bit taller though 5-7,5-8.
Unfortunately when we've chatted with women, both age group and pro's, about aero suits the response is often along the lines of cute first fast second. We encourage everyone company we test for/with to do a women's specific suit not just an xxs or xs men's. The demand just hasn't been there in the past. This is the first year where > 30% of my females are racing in sleeved suits. It's been >30% of the dudes for at least 2 years now.
If you've got any questions about aero suits or what makes them fast etc, feel free to PM me.
