Made with milk: -
Ice cream. Of course.

Creme fraiche.
Yogurt. Especially, drinking yogurt. Long been a fan of that.
ETA: I can't believe I didn't think of cheese and chocolate!!!
Clothing: -
It's funny how, looking back, some clothes hold/held really sentimental value. Even if only in memory, now. A tiny tee from a family vacation to the Caribbean (I still have that one); dungarees with a Snoopy patch; a sunhat that had a particular scent (nice one, I promise!!

); a tee from my student summer in the U.S. etc. etc. .
ETA: Yes to cosy PJs, thermal leggings, soft fluffy socks, meaningful tees, turtle necks and blankets.
And I have to say, wearing a uniform all through teenage school years saved a lot of stress and, probably, money!
