Does anybody know what the name is for the type of rayon cloth that so many 1940s/1950s dresses are made of? Thin, a little slippery? I'm finding it very hard to track down for my own sewing. Should I just look for lightweight rayon dress/blouse fabric?

The internet was so adamant that I was wearing the wrong bra size that I bought a 34DD online. It came today, and I'm pretty happy with it - 36 was definitely the wrong band size, why do so many instructions for measuring say to add 4 inches to your underbust measurement? Because it was from a larger-sizes store, it's that old-lady/vintage "full coverage" style. On the one hand, this won't work with probably most of my dresses. On the other, it's much more flattering, with more lift, I think.
