Autism and Issues with workplace dress code

Hi all,

Iv recently been diagnosed with ASD and was wondering if anyone had ever felt uncomfortable with a companies dress code?

My workplace is changing from casual to suits (Formal) even tough we don't see anyone and work purely by phone. I find suits very uncomfortable especial the restrictiveness of wearing a tucked in shirt to trousers and have always opted for black jeans in the event of a one off occasion.

Wearing restrictive clothes general causes me to sweat (To the point I would be asked if I just got out the shower) and feel really hot.

I was wondering if anyone knows if there is anything I could do?

Has anyone else had this issue?

Would it count as a reasonable adjustment to wear dark jeans? If so would my employer have to allow it?

Thank you and please leave any other thoughts as it is of interest.

Thank you,
