I’m absolutely in love with my hoco dress! The quality is amazing, the fabric is soft and comfortable, and the fit is perfect. It’s stylish, flattering, and looked stunning at the dance. I got so many compliments all night long. Shipping was fast, and it’s totally worth the price. Highly recommend!

Frequently asked questions

What should I wear to a wedding as a guest?
Follow the dress code on the invitation and choose a dress that is comfortable for the ceremony, reception, and weather. Avoid white, ivory, and anything that could distract from the bride.
What do black tie, formal, cocktail, semi-formal, and beach dress codes mean?
Black tie means a formal floor-length gown. Formal means floor-length or elegant midi. Cocktail means midi or knee-length. Semi-formal means a dressy midi or short dress. Beach means light fabrics and relaxed silhouettes.
Can I wear black to a wedding?
Yes, black is widely accepted for evening, formal, and winter weddings. Check the invitation and the couple's cultural traditions first, and style it with lighter accessories if you want a less formal look.
What colors should I avoid as a wedding guest?
Avoid white and ivory, which are reserved for the bride. Some cultures also avoid red or black, so check the invitation or ask the couple if you are unsure.
What should I wear to a fall or winter wedding?
Choose richer colors such as burgundy, emerald, navy, or champagne, and fabrics such as satin, crepe, or velvet. A midi or floor-length dress with sleeves works well for cooler venues.
What should I wear to a spring or summer wedding?
Chiffon, linen, and lightweight satin in pastels, florals, sage, dusty blue, or blush work well. A midi or flowing maxi dress is comfortable for outdoor and garden ceremonies.
