No not at all, I hang dry. Sizes are very much true to size. I don't like tight fitting so I ordered a medium-fits perfect I am 5'1 98 lbs
I would definitely order a larger size. They are 100% cotton.
I orderd two shirts and they run a little smaller than expected but I'm small framed anyway so it won't make a difference for me. I would, however, recommend ordering a size up to compensate for shrinkage.
