Many images here focusing on hips and buttocks in women.
Overall hip circumerence and buttock size are not reliable indicators of physical gender congruity, because it is heavily influenced by the model's BMI. Hip circumference is not only determined by skeletal proportion, but also by soft tissue deposition around the pelvic girdle, which accentuates the gluteal regions externally and stresses skeletal articulation internally.
Most slender girls have an intrinsically gynaecoid pelvic architecture, but have biometrically narrower hips due to their low BMI and relative lack of soft tissue. In contrast, a woman may have an android pelvis that is fortified by a heavy layer of soft tissue, but by your criteria would be more "feminine" than the comparative ectomorphs. This is why internal pelvic measurement (as determined on pelvic examination of perinatal women) is a more reliable predictor of safe vaginal delivery than external hip circumference.
There are visible idiosyncracies of external pelvic shape which serve as superior indicators of underlying morphology, which people may notice with or without conscious acknowledgement. I personally believe that these are significantly more important considerations in the gender discernment process. All things considered, I would also say that the swimsuit models here fall well within normal population variation.
