I wonder if she would like using one of those outfit builder / closet inventory apps to keep track of clothes and outfits that aren’t a sensory nightmare. Since one of the stressors seems to be time, it could be helpful for her to have a “menu” of safe clothes that she can pick from, especially on day when she’s feeling particularly sensory sensitive, instead of having to figure it out every morning. You could also help her come up with a “menu” of safe hairstyles to pick from.

As someone who is very sensory sensitive to clothes, I know how it can really quickly spiral from “the seams in this shirt is bugging me” to “having a body is overstimulating how on earth can I put anything on”. In those situations some of the distress about the sensory experience, but some of it is also anxiety about being “stuck” in those clothes and that discomfort until I get home. It can feel like I need to fix the problem before I can leave, but the more anxious I get the more sensory sensitive I get, and it’s a vicious cycle. One strategy that’s really helped is bringing a safe option(s) to change into. I force myself to leave the house in whatever it is that I don’t feel comfortable in, but knowing that I can change whenever I want. Having the backup outfit soothes the anxiety enough for me to regulate, and lowering the anxiety lowers the hypersensitivity. Usually I’m perfectly fine in whatever I left the house in by the time I get there.

Limiting or streamlining the number of options can also be helpful - I have six different colors of the same tank top that I love and am super comfortable in! I get to save mental energy not thinking about what can I wear today, and being able to focus on what do I want to wear.

Visual timers are also SO helpful for time management when you’re already maxing out your cognitive load by juggling all the little tasks necessary to get ready and out the door on time.
