If it's just the writing that irritates her skin, I would buy iron on fabric applique and apply it to a piece of cotton. You could iron on a cotton square on all her clothes very quickly.
Also, my children have never liked wearing the nighttime pj's. I just put them in sweat shirts and pants to sleep. For the summer, my kids would always be so hot and they would sweat in everything. I just let them sleep in their diaper or underwear. It prevents them from sweating in their sleep and exacerbating the eczema. Cotton T-shirts and shorts for pj's works too.
My kids would never keep their blankets on while sleeping, so I put on regular sweat outfits or cotton shirts/shorts for sleeping to keep them warm. I used to keep a small space heater and fan in their room to regulate the temp on top of central air.
