In my case, the effects of HRT are definitely helping me when viewed from the backs and sides (and it's giving people the idea that with my stomach I'm like 8 months pregnant!). But definitely my breasts are helping, as well as my earrings and ponytails and scrunchies.
Plus I'm a dress and skirt girl plus over the last two months I've been enjoying wearing pantyhose and to many people dress/skirt/hose is a very feminine look that people just link to a woman. Plus because of my intersex condition, even with my blue light glasses, my face has really feminized (I do have some masculine bone features but they never developed that deeply, so my face has always been androgynous) and having bangs help hide those light masculine features.
And that seems to be counteracting what I had thought might be a big hindrance and that's my height (in October the nurse with the bariatric program took my height and put me at 6'4" which is 3 inches shorter than when I was last measured at 6'7", but with that we both agreed that that 3 inches is probably from my pelvic hip rotation as my body has been on HRT for 3.5 years now, and that's why I'm now seeing my rear getting that bustle look).
