I have a pretty big box of stuff set aside for the sisterhood. The fun part is most of these clothes have come from other bandsters, so it's not their first sisterhood trip.
Generally, the stuff is 3x and 26/28. Some are smaller sizes, but runs big(ger).
I have yoga capri pants, a really cute strapless brown dress from Joey, lots of short-sleeve shirts, tanks, denim capris, and more. Most of the shirts are work appropriate, assuming you can wear business casual.
If you need anything in those sizes, let me know, and it's yours. And if there's something in particular you are looking for, let me know. I'm happy to take pics and post them, but I know there aren't tons of us who wear that size, so I don't waste my time if it's not necessary.
Long live the sisterhood!
