Old daughter that has the same issue with underwear, swimsuits, pants and esp socks. She has been diagnosed with SPD and has other things that trigger a reaction but clothing's a big one. I to suggest you get in touch with catch we went there and the staff are unbelievable. They're very knowledgeable, friendly, understanding, and treat kiddos and parents with sensitivity. I highly recommend them. Also I've been there if you ever need someone to vent to pm me anytime.
