Trapeze harnesses

What is the best way to wear a trapeze harness? Over the years, I've tried over the life jacket, under the life jacket, with splash coat, without splash coat, with and without rash vest, etc etc etc......Looking in any typical sailing magazine, there seems to be a lot of different options. The reason behind this, is for kids wearing a trapeze harness. My 10 year old daughter like to be on the trapeze, but her life jacket always seems to ride up to high and no amount of adjusting of harness or life jacket seems to get it all to sit right...any suggestions? 

I wear my bouyancy aid over my trapeze harness for the reason that if I get trapped under the boat, I can take it off to prevent the aid from trapping me up against the hull because most of the "new-design" boats don't have an air-pocket when fully inverted. However other people wear a harness over their bouyancy aid so that if the hook snags on any part of the boat, they can release themselves from their harness..... I prefer the option I use because harnesses can have parts cut away with knifes, whereas it would be really hard to take a harness off then a bouancy aid off when being pushed up under a hull with no air. I also feel more comfortable with the straps closer to me than over a bouancy aid. If your daughter has draw strings at the bottom of her life jacket, make sure they are as tight as possible.

first time i trapezed was at the age of 3. there my father wrapped me up in a wetsuit over it my mini harness and then over the harness the bouyancy aid. was no problem then as far as i can remember and all the kids i teach how to trapeze i tell to do the same. it seems to work!

my favourite ever bouyancy aid was the one i had when i was a nipper, it had the little foot loops to step through so that it couldn't ride up. Why don't more designs have this? I've been experimenting with different combos over the  summer and i've settled on rashy/wetsuit/bouyancy aid/(rashy or spray top)/harness. I have a nappy harness with covered adjustment buckles so there is no problem with getting caught on anything so i like to wear it over the top and it also helps to heep the life jacket in place. I  hadn't really thought about the safety implications of the different layers I just hope never to find myself in that situation.

well i don't want to start the skiff/non skiff debate again but i do sail a twin wire cherub. I always wear a life jacket because thats the rules isn't it?! Where i sail inland they try and make the windsurfers wear life jackets!
