Rayyan wears a very pretty blue outfit of a long turquoise tee with a bit of embroidery over navy trousers.
As usual Shukr has the best set:
Shukr's Soft Cotton Shirt with Tucks in Oceania for USD $48.95
with these trousers:
Shukr's Wool Flannel Pants in Navy Blue for USD $19.95 or for a wider trouser try Shurk's Lengha Pants for USD $48.95
I know I use Shukr alot, if you would rather I used some other site please recommend me one in your comments.
