"Resting Mom Face (RMF)" Soft Cotton T-Shirt. Resting Mom Face is the look all mamas have after they've spent all day doing mom stuff. It's the look that says we're tired, but we love it so much. This t-shirt was designed by moms for moms, who might or might not wear it while holding our hands to our forehead. This RMF t-shirt lets you showoff the fact that with or without that chronic RBF, you're a pretty rad mom who's got this!
