Bridal design is really a small number of silhouettes, and once you can see them the whole category makes sense.
Ballgown, A-line, sheath, mermaid, empire. Each one does something specific to the proportion, and the decoration on top barely changes that. A heavily beaded sheath is still a sheath. Trying several in a row is the quickest way to see which shape suits which character, and it is much more instructive than adding detail to one.
Pick the silhouette first, every time. Everything else is finishing.
