Matching, as I was taught by my Mother, who was always dressed to 'perfection', at ANYTIME, & I was so proud to be in her company, anyway.
If not matching, I feel very 'uncomfortable', & quite 'out of sorts'!
My whole outfit, from the simplest, to evening wear, ALWAYS matches, & it makes feel not only well dressed, but also a million $....
Mum always said, 'you never know who you might meet'! It's proved a very true maxim for me on many an occasion! The best example was when the Governor was in my row at a Concert, & had to go passed me to her seat!
To me, good habits formed from childhood onwards, are very hard to break!
