Clothing is a nightmare

Thank you all for your advice, I really appreciate that you have took the time to read and reply. 

Most of the tshirts he has have a transfer label on them instead of a meterial tag, I have tried so many ways to get them off but haven't succeeded.

He hates clothes shopping, I get him to try things on that he likes, he says they are fine. I buy them, then he refuses to wear them.

It's only been the last few months that this has been an issue. However I will try everything that has been mentioned. I just want him to be comfortable and not get frustrated with himself.

Perhaps he does what I used to do, which is just to say "yes it is fine" in order to stop my mother asking me questions I could not answer, such as "does it fit?"and "does it feel comfortable", and therefore be more quickly able to put on my old clothes and leave the 'horrible' shop! I used to hate the lights in changing rooms, the heat, the smells, the clanging doors, the coat hangers rattling, the music, all with the pressure of being asked if something "fit" when EVERYTHING felt uncomfortable to me. Just trying on things, my skin used to go all red and blotchy for some reason and I would feel so hot and bothered. I can still remember the relief of walking back out of the shop doors!
