Sensory issues with school uniform

My 15 year old daughter has high functioning autism and has always had sensory issues with clothing such as not liking certain fabrics, seams, etc. Recently she has developed a patch on her neck which has become super-sensitive during the last few days preventing her from wearing her school polo shirt. The patch does look a little inflamed, but although various creams seem to have calmed it down visually, she still goes into meltdown when she tries on her polo shirt. Because of this she won't go into school and although she would be allowed to adapt her uniform to reduced the sensitivity, she still refuses to go because she would look different from the other girls and she is extremely self-conscious.

It would be great to hear from anyone else who has had a similar problem or has any ideas on what might help this situation.
