A'salaamu alaikum ya'll. I found this very hijab-friendly tshirt while looking for bras today. (I really wanted to say "whilst" but refrained as I am neither British nor Canadian). It's 39" long (yes!) has long sleeves and a modest neckline. It comes in sizes M to 6X masha'Allah. It's only $9.99 and comes in 4 colors although some are sold out. Go here to check it out.
I've ordered a heather blue and a heather grey, opting out of the red and magenta. Yeah you know me, not too exciting in the color palette department. :-) I don't normally buy in multiples anymore but this seems like such a great shirt for exercising (um, I do it sometimes!) or just spending some time at the park.
Ma salaama ya'll!
