Gal the big bouncy waves/curls looked lovely on you
Mine was always curly/wavy and so much of it, but fine hair so it was easy to curl any which way and it stayed in.
I used to wear it up a lot but for a pleat would just do it like the first part of that video, all in together; from the nape of the neck twist upwards then fold the ends down in and pin the top part of that or however much needed it. The front would sort of settle into place
Easier to do if it's blow-dried first, and hairdressers would say better the day after it's washed, it will hold in better.
Those with less/thinner hair I think are supposed to first dry on those big rollers, to give the body needed, but that's for if you want it to look really good for a special occasion x
