Yes, I recently looked at a photo of myself as a youngish woman, (early 30s) and thought I looked good then, much better than I remember ever thinking at the time.
I too had an 18 inch waist when I was sixteen - to hear my mother you would have thought it was my only good feature.
Waist long gone, but my eyes remained looking nice until quite recently when thyroid trouble kicked in.
One thing is that young girls never think they look nice, but we, their older relations, could and should do a lot more to point out their good points to them and bite our tongues before mentioning anything that strikes us as less fortunate.
