Hi Daisie!
I loathe stockings and suspenders, in my opinion a more ridiculous, uncomfortable and impractical item of clothing has never been invented
however the clients love them so I don't have the option of ditching them!
I don't know if anyone else does this, but I put the stockings and suspenders together first, then put them on like a pair of trousers. (Not in front of the client, obviously) It's the only way I can do it, as trying to attach a tiny fiddly little hook and eye at the back of my own arse I find near impossible.
Putting your knickers on over the stockings and suspenders is also a good tip, then you can keep your stockings on when doing the naughty and you don't have to keep taking them off and putting them back on again.
