Hmm I’ve been cogitating on this one!! – Not like me to be so open honest and frank about things – hopefully this will encourage others to enter the debate and produce some interesting comments!
I’ve been aroused by, and aroused whilst wearing rainwear for as long as I can remember. So, like many have said on page 1 – self-gratification whilst wearing it or onto said rainwear is one aspect!
Secondly, it’s got to be just wearing them whilst doing what they are designed to do – in the wet! Nothing better than being fully togged up in cagoule and waterproof trousers on a miserable day with the swish-swish of the material and the sound of the rain on your hood.
Thirdly is one that has troubled me off and on over the years. We seem to be drawn to wearing Ladies rainwear! Is this because it’s predominantly Ladies Macs that are produced in the materials we enjoy / adore – PVC. Or is it that we enjoy an attractive lady in a nice shiny mac OR is it the thrill of illicitly wearing something we shouldn’t! In this respect I’ve got several ladies Berghaus and Regatta raincoats (Various colours – Grey, Purple, Blues and Burgandy) that I wear regularly in normal situations (school run / work etc).

No one has yet said anything (they are sort of unisex) and I get a real kick out of knowing that I am the only one who knows why / what I am wearing. Or as per 2 above – wearing one of my Primark PVC raincoats in public in the rain

Likewise an equal thrill is wearing someone else’s rainwear. I’ve commented before on the first time I wore a Peter Storm cagoule when I borrowed my Girlfriends or getting the latest mac from eBay that still carries the perfume aroma from the previous owner!
Finally – a more recent aspect of my rainwear fascination! Something that started a couple of years ago. I enjoy seeing attractive ladies in rainwear. I get a real kick seeing the bound and gagged in rainwear and high heeled boots; struggling against their bonds as they try to set themselves free: the crescendo of creaking PVC and harrumphing behind the gag! It is the ultimate in sensory deprivation / overload. Bound and gagged in a crinkly mac with the hood up leaves you in splendid isolation and what better than seeing / hearing it than trying to recreate it yourself. Thus I have found myself indulging in a bit of cross-dressing and DID role playing. Trying to be that fantasy / image! Boots, pencil skirt and Primark mac being my favourite combination. Time alone is rare but on one occasion poor
Wendy 
did just a little too good a job of tying herself up to the chair and was very lucky to get fee – I’d never drooled whilst wearing a ball-gag before but

Once, when having the house to myself for an extended time I went further. Painted nails, wig, and make-up. Stockings and suspenders, PVC maids outfit and thigh length boots and Wethervain PVC trench coat tightly belted. The chair tie lasted several hours and then I dropped off!! I’ll never forget that moment of waking, slowly realising what I was doing / where I was – magical!
Finally, my other half knows nothing about my rainwear interests (she should have worked it out though – I have enough!) But, whenever she wears one of the 4 Primark Macs I have bought here – she always gets appreciative comments from her friends / people she meets. I guess it’s as a consequence of the ‘Festival scene and the great British climate’; I’ve even had to source one from eBay for a friend of hers!! I used to ‘borrow’ he blue one and now have my own in Blue & Green that she knows about – (I have one of each colour produced for both of us!!) which I wear regularly around and about. Several times I’ve worn them at theme parks on wet days or on the wet rides!!

Only once has someone commented on my attire “why are you wearing a ladies coat”? . . . . . . . “Because it’s wet, it was to hand and it’s keeping me warm and dry – any fool can be cold and wet!” Sometimes I think out biggest prejudice is ourselves. After all – why is it perceived to be okay to wear a plastic poncho at music festivals but not a coat!!!
