This is a look known and loved and blogged about half a dozen times. Plain black abaya, black shayla, and punchy accessory (in this case a yellow handbag).
This is how a designed an old set for BM. Only in IRL, I like looser cut abayas (like overheads or butterflies) so this is how I wear it, with a sleeved butterfly abaya from http://www.sunnahstyle.com/product_info.php?pName=ruched-satin-sleeved-butterfly-abaya&cName=abayas-butterfly for $49.99 USD. I trust Sunnah Style. They are accurate, have good quality for their prices, and deliver ASAP. I have never been unhappy with anything I've got from them.
