Looking at these tips from the fashion industry..dancer9, I haven't met half of these tips.

My idea of fashion treating myself is a good haircut.
I gave up wearing fingernail polish ...over 1/4 century ago. I just make sure my nails are clean and neatly cut. People might look at my hands, when I demonstrate something on the computer.

would agree wearing 1 colour head to toe is slimming...if it's not orange...

And a purse..1/2 of the time...it's a bike pannier. I actually spent some time last week, trying to find a tiny, flat unobtrusive purse that was lightweight to carry inside pannnier but I could take out to use when going to a nice restaurant/store off-bike during an evening out. Haven't been successful so far.
