Small casual weddings and micro weddings are all the rage now due to obvious reasons and it seems that this trend will stay with us for long. What to wear to a simple wedding, a casual backyard or a casual modern one? Here are some outfit formulas for those who are invited!
Casual Wedding Guest Dresses
A casual dress will be a nice idea as it’s easy to style, it always looks cool and chic. You may go for a slip dress paired with a t-shirt, a turtleneck or nothing at all – just some flats and a blazer if it’s chilly outside. A basic mini or midi dress of your choice will be a great option for a spring or summer wedding, and you will need only some shoes and a bag. To make your look catchier, choose prints like polka dots or florals that are timeless for special events.
