I've been wearing Perry Suspenders for about 20 years. Previous to that, I tried about every kind, even the kind that require buttons on the inside of the waistband. I started out with the 2" wide Perry's that have the plastic slide for the adjustment for length. I then tried their "dress" style suspenders which are about 1 1/2" in width and have metal "buckle's to adjust the tension. These work very well for me.
I wear them over a Duluth Buck naked tee or undershirt and either underneath or over the top of a long sleeved shirt depending on whether or not I have my shirt tail tucked. It is the plastic attachments that fit over the outside of my belt and slip up on the underside of my belt to hold them in place that I love so much. They are easy off and easy on, but the best part is that when it comes time to take a sit in the men's room, all I have to do is slip the straps down and off my belt and let the suspenders hang underneath whatever I am wearing on top of them and my britches can be taken down in the normal fashion without having to undress or fight with the metal clasps to reconnect them to the waistband of my britches. Get up, pull britches up, tuck shirt or not, reattach the rear hook on my belt, then reattach the two front hooks and I'm good to go. The hooks over the belt are not bulky and are very secure. And the metal adjustment buckles lie much flatter and stay in place better than the plastic slides on the wider suspenders for me.
I have a few sets, the newest ones for wear other than when am working and sweating heavily, and the older ones for work duty. As does all elastic, they eventually stretch to the point where they go in the can and I make a rotation of the newer ones to work duty and replace the newer ones with new. I get years of wear from a pair and keep my newer ones looking more spiffy for everyday wear in public.
My suspenders are seldom seen, since normally when I do tuck my shirt tail, I wear a vest of some kind over the top so both my galluses and my EDC are covered and concealed. I highly recommend the Perry's. Iggy's suggestion looks very promising to me, but I prefer the single strap down to my belt (which covers the center belt loop of my pants over the belt). I can't imagine doing without them at this point. I suggest you try a pair and see what you think. They'll take some getting used to, and you will learn to properly adjust them to hold things up well without being too tight. I buy them online from PerrySuspenders web site and have never had any kind of issue with the companty over the years. They are a great product in my experience!
