What specific user problem will AR + AI solve for clothing try-ons?

Online clothing shopping is basically a gamble wrapped in a dissapointment burrito:

• Sizes are lies
• Models look nothing like us
• Returns are a second job
• Lighting makes everything scam
• and many more...

So, what real, day-today problems will AR + AI try-on tech actually fix?
Curious what everyone thinks the first genuinely useful application will be.
