Sunflower Lanyard

There are also some bag tag things you can get.  I got some of these mainly so that people could see them from behind when I am using a backpack.

You could always carry a NAS Autism card as an alternative. I carry one with me even when wearing my lanyard as it has extra information to help. Failing that, there are a lot of amusing autism T shirts for sale and humor always works well. 

You could try putting one arm through the lanyard, so it sits on one shoulder and runs diagonally across your front and back. That's what I used to do back in the days when I carried a camera around on a neck strap. It also stopped it from dangling in my soup, which was nice.

I sympathise - I also find necklaces and lanyards irritating. I don't wear a sunflower lanyard but if I started to I would try getting some soft polo shirts, so that the lanyard wasn't against my skin.

Thank you for this!

I posted about these other items just before your reply :)

The patch comes in a bundle with the pin badge. 

The only reason I didn't mention it is because I find such embroidered patches to be just as intolerable, on single-layer clothing, as I find the lanyard is on the back of my neck.

I can't wear v-neck t-shirts for the same reason (the lower part of the opening feels too uncomfortable against my skin), or tops with heavy-feeling transfers / prints on the back or the front.

All great advice and ideas, thank you so much!

There is also an embroidered / woven / fabric iron-on or sew-on badge (to add to comfortable clothing or bag you already own):

"The Sunflower embroidered patch and pin badge are perfect alternatives to the lanyard which can be sewn or ironed onto your jacket, bag or any garment to show you have a disability that is not visible.":

Also, they now do a 100% cotton t-shirt (adult and child sizes) with a printed "lanyard":

...plus lots of other accessories too.

You're welcome!

I wouldn't wear the round, pin badge with a single-layer top like a t-shirt, because the butterfly clip at the back is quite prominent and would feel too uncomfortable.

But the ribbon badge is only attached with a very small safety pin and is very lightweight. There need only be a tiny section of the pin on the inside your clothing. 

If neither are tolerable, the wrist band is still a good option. It's also easy enough to raise your hand and gesture at it if you need to actively draw someone's attention to it.

There are some other options, too - including a t-shirt with a pre-printed lanyard image, armband, bag tags, and a baseball cap:

Ooo thanks this is a good idea. Did you find like the metal bit of the pin was touching you at all where you have it attached or not really? 

Depending on what I’m wearing, I have the same issue with the lanyard.

As I do, you could instead wear a chest ribbon badge, pin badge, and/or a silicone or fabric bracelet:

My GP recently complimented me on my ribbon badge
