We have Tricot!
If you love Tricot and can't find any right now because the country is missing its Tricot, we have Tricot in Midnight. The Midnight Tricot Bundle is sold in one yard land 3 yard lengths so you have plenty of fabric for more than one project. It's also sold in Kit Cuts and 1/2 yard cup lengths.
Our tricot might be the loveliest tricot out there. It's great for bra cups, supporting most bust sizes, and is also used for panties, slips and camisoles. It is relatively opaque and provides very good coverage. There is a 15 - 25% give in the fabric on the crosswise dimension, but no stretch. For bra cups, you can line the cups with the give running in the opposite direction to stabilize it. It is smooth and liquid, it doesn't ravel and feels lovely. Clothing will glide right over it.
