Is there a type of dress attire between dressy casual and semi-formal?

Cocktail Attire

Business casual is probably what you are looking for. This includes nice slacks and a button down for men and a dress (or pants) and a nice blouse for women. This is how most people dress for work however. Without knowing the event it's a little hard to give more information than that. If you are truly going for a notch below prom (which is considered formal attire), semi-formal is appropriate. But, again, I'm not sure if that is truly appropriate for the event because of lack of detail.

informal is like khakis and a golfing shirt for adult males. intense high quality pants, khakis or a intense high quality-ish gown for a woman. something cotton, linen, etc. Semi-formal oftentimes skill suit for the adult males with a tie. For the ladies, that's totally complicated. it is not extremely Oscars intense high quality (which would be formal), inspite of the incontrovertible fact that it remains appropriate to placed on long outfits, fairly interior the night, yet no longer something with a practice or great-sequined. it extremely is a step above what you may placed directly to church. think of satins and intense high quality silks. additionally, in case you would be donning it interior the night, you're expected to be greater formal than for a morning or afternoon journey. incredibly, it extremely is an outfit via outfit determination. additionally, shop in mind that upload-ons like rings and shoes and hair can take an off-the-cuff outfit and pump it as much as semi-formal. desire that facilitates!

if u want suit/ties it won't be business casual. there is NOTHING casual about a tie. what u described was business. if u write formal it would mean dark suit and white shirt. women will wear dresses in any case
