@Shelly24 - After experiencing the same thing and reading reviews on the site where I buy from, I’ve found there’s a difference between “hold ups” and “stay ups”.
From what I can tell, stay ups stay up on their own, hold ups need to be held up. I bought hold ups and they kept falling down without the suspender, but the stay ups stay up without.
From the name, I thought “hold ups” would stay up on their own.
That’s brilliant thank you! I have never heard of stay ups!! I’ll have a look. 
There’s all sorts of information on different sites, but just the one I buy from has the 2 types, and a lot of complaints about hold ups falling down. 
Haha I always struggle with this.
What I do it I turn my right root out and twist my body. I also make sure I loosen the straps the most they go as it’s so much easier to attach that was and then I tighten them afterwards.
Hey @Kitty-Cat01 that’s brilliant thank you so much!
@Delboy1991 I don’t know why I never thought of this 
been twisting in front of mirrors, legs over head trying tog et the back ones done every time
@Utah1997 - it’s a great stretching routine though.
@Jade48 i even tried the trick on the chair and being one legged was definitely not great for my balance!!! after a while you are right you get used to the stretching!
Definitely showed up my ex when I was better at attaching them than she was
@Utah1997 - following some advise on here, I tried just putting them on as normal, just with the straps loose, it worked a treat, but seemed to take the fun out of it. 
I’ve tried putting it all together like a kitset, attach the stocking to the suspenders before putting them on. Doesn’t work for me, so perservere with the loose straps then tighten them when in place.
I just can’t wait to try and figure this one out with my new lace body suit with built in suspenders, 3 straps on each side. I should record this one on video, in case I don’t make it!
I will look forward to seeing that video. @Jade48
I used to struggle with them before but I’ve learnt it’s best to have them all at their max length, attach them, then tighten them to where you want them to be. It makes it a lot easier 
!
Hold ups unless you really like framing the twig and berries with suspender straps.
Why have I only just come across this post… I think more woman should know things like this got my new LH suspenders and underwear to try out so will give the new method a try!
It’s still fun trying at every given opportunity.
I’m going to experiment with my new knickers with built in “removable” suspenders. I’ll attach the suspenders to the stockings, put the knickers on then put the stockings on and attach them to the knickers.
Neither of us are massively turned on by suspenders and stockings and the faff assembling them really isn’t worth it for us. Fortunately most of the LH lingerie has removable suspenders which is perfect. If we do occasionally want the look then we go for hold-ups.
If you are wearing seams - you’ll need some help getting them pin sharp straight - the help from an OH is ideal for this. Before they get messed up of course……
@Delboy1991 - Genius! I shall be telling my wife this little tip-bit. She likes the idea of dressing up for me - but loses her mojo if she has to ask for help! This will help!
My wife attaches them first to the outfit & slides it on as a all in one
@k8xxx
Ok, so knickers with detatchable suspenders! I tried putting the knickers on then attaching the suspenders to the stockings, putting the stockings on then attaching the suspenders to the knickers. It worked but I still had to loosen the suspender straps.
Then I assembled the whole thing, knickers, suspender straps and stockings. Then I just put the whole thing on as one. It was more like just putting a pair of tights on, so seems like the best way to do it.!
