The whole deal is a marketing flog fest for new shinies with the latest added value, added to the fact that the smallest facets of your life will become monetisable and surveillable , there is nothing that will escape connection.
Your shoes will tell how far you walk and how often or how fast, so that your life/health insurance will tell you ' You are a lard arse your health problems are self inflicted so we won't pay out'
I haven't figured out what your underwear may say about you but it will in all probability say something.
Outerwear will probably contribute to powering the rest of your kit so if you are not wearing generative clothing you will be considered anti social by contributing more CO2 into the environment.
Hats will become fashionable because they will have inbuilt EECG monitors that will enable your brainwaves to be analysed along with physiometrics captured by public and workplace cameras to determine your social/anti-social/terrorist potential.
Aside from that the ability to apparently decide in microscopic detail what your buying preferences are will result in the perfect advertising campaign aimed at you personally.
And that's without even getting to what your house/car/workplace will do.
What a marvelous future the young can look forward to.
