|I have been reading the Jeans Sew Along threads, and noticed that many of you have been having trouble with your waistbands stretching out by the end of the day. I have not made my Jalie Jeans yet, but have purchased many stretch jeans that fit me really well in the store, but by the end of the day, my pants were saggy because the waist had stretched out. I purchased one of these invisible belts, and my jeans stay in place all day. Not only do they stay UP, but it seems like they stretch much less widthwise as well.
I know that some of you are interfacing your waistbands to keep them from stretching, but the invisible belt, being elastic, gives you room for those daily weight fluctuations, that you can't get with an interfaced waistband
My theory is that the fabric probably has stretch both lengthwise AND crosswise, and if it can't stretch lengthwise (because it is sitting tighter on your waist, it can't stretch as much crosswise. At least it works for me!!
Note that this belt isn't TRUELY invisible, and is made to be worn with shirts and tops that are not tucked in. It doesn't add any bulk to your waist as you might have wearing a regular belt under an overshirt.
The elastic used is clear but seems much thicker and stabler (is that a word??) than the invisible elastic sold for sewing. It is adjustable, and the hardware is much like the kind of hardware used in bras. The width is about 5/8"
The belt itself is a bit pricey (17.00), but could probably be made yourself. At the very least, you could try to pin some invisible elastic through you jeans belt loops and try it, to see if the idea would work for you.
This is only one website that I found. If you Google "invisible belt" you will find more.
