Well sounds to me perfectly all right for a woman between 55 and 65

- Would be a bit more odd for someone in the late 30ies maybe. But it all depends - not only on age and occasion but also on the cultural background, the region and all that. And of course that does not mean everyone has to blend in. Heck I was dressing goth for some years after transition - not exactly blending in and trying to wear what others did

- but it was obviously meant to look individualistic, so that was accepted well

- Oh and yes - since many TS look a tad younger at least in their first years after starting HRT, why not dress a bit more for the age one looks like - thats quite ok.
