While Googling "pink abaya", I found this website: www.renukasilks.com.
They have a particularly lovely abaya (two-layers, with buttons at the top of the outer layer) on page 3 of the "abaya/jilbab" section for $45. You can get that style in two-tone pink, two-tone gray, yellow and purple, blue and purple...etc. So many options! And for about 15 bucks more you can get the matching hijab and niqab.
