pba, If you read this thread you will see that this is exactly what we are discussing – the y”h to dress in a not tzniusdik way, and how to deal with that nisayon.

As far as your practical questions — even when one is no longer “growing”, women are constantly changing size and shape, and outfits that were ok at one point may no longer be appropriate, but since they are sitting in your closet, they present a BIG nisayon on a regular basis as a result of this y”h.
