What is the difference between semi-formal and casual attire?

Both semi-formal and casual attire have their place, but they cater to different occasions.

Semi-formal attire is more polished and elegant than casual clothing, requiring dresses, skirts, or tailored pieces, whereas casual attire includes relaxed, everyday clothing like jeans, t-shirts, or sneakers, as explained in semi-formal wedding do's and don'ts4.

Key distinctions between semi-formal and casual wear

  • Fabric: Semi-formal pieces are made from luxurious fabrics like silk or chiffon, while casual wear leans on cotton or denim.
  • Footwear: Semi-formal calls for heels or dressy flats, whereas casual allows sneakers or sandals.
  • Occasions: Semi-formal is suited for weddings, cocktail parties, or business events, while casual is for day-to-day activities.

What should you not wear to a semi-formal wedding?

Certain outfits can feel out of place or inappropriate at semi-formal weddings.

Avoid overly casual outfits like jeans, sneakers, or t-shirts, as well as overly formal gowns that may upstage the bride. Distracting patterns or bold, neon colors are also unsuitable.

Semi-formal wedding don’ts

  1. Too casual: Items like shorts, flip-flops, or graphic tees break the semi-formal dress code.
  2. Too formal: Floor-length gowns or heavy embellishments might feel excessive.
  3. Bright colors: Neon or flashy tones can overshadow the event’s aesthetics.
  4. White or bridal hues: Reserve these colors for the bride.

What to wear instead:

  • A midi wrap dress in pastel or muted tones.
  • A chic jumpsuit paired with dressy heels.
  • Accessories that complement the dress without dominating the look.
Avoid This Choose Instead
Jeans or t-shirts Knee-length dresses
Floor-length gowns Midi or tea-length dresses
Neon colors Pastels or jewel tones
