First and foremost, wear something you can dance in - something dressy-casual and something that makes you happy! The evening will be spent outside, and Colorado weather can be pretty fickle - so layering might be a good approach! After the sun goes down it may get chilly, too, so a light sweater or wrap would probably be a good idea!
We love your kids! Truly! We do! But with a limited number of guests that we can invite, we had to get creative. So, we ask that you take the night off of parent duty! If you need a recommendation for a babysitter, don't hesitate to ask.
If your invitation was addressed to yourself + one special guest, then heck yes! Bring 'em! If it was only addressed to you, then we ask that it just be you!
