What is the difference between all-over lace and lace appliqués?

All-over lace creates a continuous pattern across a large area of the dress. Lace appliqués are individual motifs, such as flowers or leaves, sewn onto another fabric. Appliqués can frame a neckline, define the waist, or gradually trail down a skirt. Both approaches can create a subtle or dramatic look, depending on the pattern and placement.
