A lot of prominent women of Sigma sport their blue and gold. All of them will not be sporting a poodle pin every time you see them, but some of them do sport their colors and pins. This would make a better listserve discussion, though. You might want to take it there so that more sorors could give you more information.
High Profile Sigmas I have seen sporting nalia and/or colors:
1. Soror Broussard
2. Soror Rowell
3. Soror Horsford
4. Soror McCoo
5. Soror English
6. Soror Williams
7. Soror Dupre
8. Soror Rep. Corrine Brown
9. And of course, Soror Mother Love
These are the most recent ones I have seen. I know there have been many more, but I don't get out like I used to
