I'm looking for some ideas for comfortable invisible straps. I want to sew these into my wedding dress, onto the strapless underbodice, which has a sleeveless lace overlay (see picture below). They don't need to be super-strong, just an added layer of security to make sure there is very little weight on the overlay, which is a delicate silk tulle. The inner corselette will be doing most of the work in this respect, these are just an added bonus.
I don't want those plastic invisible bra straps from the noughties, as they get sweaty and gross.
I thought about tulle (I wouldn't need to finish any edges etc.) but I worry that it will stretch, and also may be scratchy. The silk tulle is way too stretchy and the next softest (polyester) tulle I have, although less stretchy, is a bit prickly.
My current best idea is a
stretched bias strip of organza. I used these to stabilise the top of the underbodice, and they really don't stretch once you have pulled and ironed them. Cut on the bias, there will be minimal fraying at the edges, so I can just use one strip and it will be pretty much invisible under the tulle.
Does anyone have any other ideas? Or can you think of any drawbacks to my bias organza strips idea?
I did think about underlining the whole overlay with silk organza, but it wasn't transparent enough.
My dress design, so you can see what I am talking about regarding the overlay:
