How to Style Your Elegant Mermaid Dress
Hair and Makeup Tips
- Updo or sleek ponytail: Highlight your neckline and back details
- Bold lips or smokey eyes: Choose one to keep the look balanced
- Subtle shimmer: Let the dress shine, not your makeup
Accessories
Keep accessories elegant and minimal:
- Drop or chandelier earrings
- A statement clutch
- Heels that complement the length and color of the dress

Choosing the Right Fit for Your Body Type
While mermaid dresses are body-hugging, the key is in the tailoring. Don’t rely solely on off-the-rack sizing—visit a tailor to get the hem, bust, and waist nipped to perfection.
