I found some wonderful sheer and silky, smooth poly/nylon sheer lingerie fabric. It is a 4 way stretch knit with approx 30% stretch one way and 50-60% the other way. It is 54 inches/137cm wide and is sold in 1/2m (20 inch) increments. Order 2 if you want a full continuous metre/39 inches. It is available in the softest blue and pink colourways. SO feminine.
If you like the look of sheer, see-through lingerie, this is just the thing! I have made panties and bralettes with this and I love it. One recent bra I made is the brand new pattern from @rubiesbras: the Sahaara bra. I made it up in the soft pink and it is so very pretty and sexy! See pic below of the Sahaara bra made with the pink fabric on sale here. I used a double layer of the fabric throughout the bra. (Bra is not for sale LOL)
Of course, it would also be beautiful sheer lining fabric for your lingerie projects.
If you do not require the stretch, then use togther with a non stretch fabric.
