A polo or button down with jeans or khakis. A sundress, jumpsuit, skirt, etc. Mountain chic hats and fun boots are encouraged :)
Rehearsal Dinner
This will be a bit nicer than the welcome party but still want to lean towards mountain chic. A jacket, no tie and cocktail attire.
Wedding Day
The attire is western cocktail/mountain chic. For the women, a dress with boots, flats, or wedges. For the men, a suit and boots or dress shoes. You will be doing some walking to the ceremony/reception spot. Mountain chic hats are encouraged :)
Weather
The average for September in Telluride is low 70s/high 60s during the day and low 50s/high 40s at night. We recommend bringing light jackets or sweaters for the nighttime festivities.
