Sue,
Yep, we've all been there. Learning to do bras up, I do mine around the back, no trouble, lots of practice I suppose. Dresses with zips on the side, left or right, same for skirts. It's something discussed here many times, and for the record, they go on the left.
Heels is a two stage process. learning to walk around the house only partially prepares you for walking outside and for any distance. Only worn stocking a few times. Holdups I feel make them sort of redundant. I can see they have a certain glamour, sexiness but practicality wins out for me.
Little skills and tricks we learn along the way. Putting a skirt over a blouse then lifting the skirt to pull the blouse down to get it even all round is one example. Then there's the first time you wear false nails and nearly take an eye out because you forgot they were longer and more pointed. It's hard this CD'ing thing.
