* Red shoes: Could work for a bold, coordinated look.
* Blue shoes: Could also work, creating a cohesive feel.
* Black shoes: A safe and versatile choice that would let the necklace be the focal point.
* Neutral shoes (e.g., nude, beige, gray): Would also work well, allowing the necklace to stand out without clashing.
Ultimately, the best shoe choice depends on the specific shades of red, blue, and black in the necklace, as well as the style and color of the dress.
