Was just looking for some advice - I've never really experimented all that much with wetlook and wet play - asides from the odd fully clothed shower. However, I am majorly into getting messy - I especially like the feeling of my clothes sticking to me, which I imagine is something that could be achieved with just water.

So... where should I begin?

some thing to start with would be oil , thicker than water, so still sticky, but clear substance ( depenidn on oil ) and easy to rinse of with lots of soap and water, so I found a good crossing over, from wet to messy so suppose it would vice versa ,but mostly just go and get wet, in the sea, bath, shower, river, (muddy if need ) garden hose . and welcome to wetlook

My suggestion would be to just go for it and to try getting wet wearing many different types of clothes as they all will feel slightly different when wet. Also try different ways of getting wet as that can also change how they feel. Try everything from swimming fully clothed to fully clothed baths and showers. My personal favorite is swimming fully clothed as most clothes cling quite nicely when getting out of the water some clothes even cling while in the water. Please keep us posted on what you try and how you enjoyed it.

I completely agree that you might like to try swimming in your clothes.
The only thing I would add is, think about doing it in public.
It's a great feeling, especially that you're "breaking the rules" and just going your own way.
No-one objects and others will secretly admire you.
Have fun.
