No, not really. I've used a wired pump for 11 years and most days just use the excellent clip it comes with to clip it on my waistband or belt. If I'm wearing a tight dress I put it in my bra bag and hang it from my bran strap under my arm. At night I use a Velcro belt with a soft case.
I got all these accessories from my pump manufacturer and I've found them really well designed and long-lasting too.
The only DIY thing I use is a Tubigrip on my thigh if I'm wearing, say, a skirt and a tight top and don't want to use the bra bag.
