FQA Peacock Blue Long Dress

This option is best for guests who want a glamorous, form‑fitting silhouette with smooth drape. The wrap design enhances the waist while the V‑back adds visual interest. A potential limitation is that the fabric’s stretch may show subtle lines on very curvy frames if not tailored properly.

Why selected: The color and silhouette deliver a striking wedding‑guest look that pairs well with metallic accessories and nude heels.
Considerations: Ensure correct sizing from the provided chart; the fabric is designed to skim curves. The dress does not include sleeves, so consider coverage with a light shawl if needed.
