I've noticed a few things that I really admire on other women but just would not be right on me:
Sleeve tattoos - think they look stunning
Pastel hair colours - pale violet, candyfloss pink, silvery grey, love 'em
Heels - cannot wear them, cannot take the pain, but really admire them on other women
Hats - especially big floppy fedora types. I wear a beanie for warmth in the winter - that's it!
What do you love on others?
