I wouldn't mind one of those ballet skirts to wear over regular leggings. Let's see, I can hear them already when I go to class at Lesley University:
"Who is that old woman in the flowery skirt? And leggings? She wants to be a psychologist????"
Seriously, I bought a Sheila Moon bolero a couple of years ago and I eventually threw it out. It bunched in the shoulders and the sleeves were still on the verge of being too long, in the extra small. The Terry one in the s/m fits me perfectly.
Off to investigate the Sheila Moon site.
