How to style Betty Sequin Strappy Mermaid Formal Dress
Classic formal polish
Pair the dress with slim metallic or tonal heels, a compact clutch, and one refined jewellery focus. A sleek bun, low ponytail, or softly controlled waves will keep the neckline and bodice visible.
Modern evening contrast
Use black, nude, or clear footwear and choose geometric earrings or a sculptural cuff. Keep the bag small and let the gown’s texture, slit, corsetry, or embellishment provide the drama.
Ceremony-ready layering
Add a satin wrap, tailored evening coat, or clean cropped jacket for arrival and outdoor photographs. Remove the layer indoors so the original silhouette remains uninterrupted.
Colour, texture and proportion
The combination of the product’s main colour and sequin already gives the piece visual character. Surround it with quieter finishes, and use cropped, tucked, or close-fitting layers where needed to preserve the intended waistline and overall proportion.
Where to wear it
This piece is suited to proms, black-tie weddings, galas, formal dinners, engagement parties, and other evening events.

Relevant supplied details include: Sewn-in knit lining; Delicate spaghetti straps; Padded bra cups for added shaping and support; Adjustable strappy tie-back detail; Back zipper and hook-and-eye closure.
Care and storage
Handle embellished areas carefully and follow the garment label, which may recommend specialist cleaning. Store the piece separately so beads, sequins, rhinestones, and delicate mesh do not catch on other items.
