If you're going for the burda 7879 pattern, I'd recommend buying it from simplicity.com instead of ebay as it's only $9 there. It also might be available in large chain fabric stores in the US (I bought a copy on sale for $2 from a Joann fabrics a few months ago). There's also a thread on danceforums started by Laura documenting how she made a dress from that pattern, although she ended up being a little disappointed by it (the pattern, not the dress - she ended up heavily modifying the pattern). I'm planning on making a dress using the skirt of this pattern and a leotard pattern I made by modifying the KwikSew Swim and Action wear master pattern. That's a fantastic book, by the way. I can't recommend it enough. I just made a syllabus dress (that doubled as a new year's dress, bonus!) and that book was invaluable. For latin dresses, Jalie has some interesting patterns that are intended for figure skating and as such already have bodysuits built into them. With a little modification, it seems like they would work well.
