26 Casual Wedding Guest Dresses for More Informal Nuptials

2. Crew Gwen Cupro Slip Dress

Pink will always be a summer favorite, and if you’re into Barbiecore, you should totally consider this slip dress. The cupro material feels like silk (but is more durable and machine washable). We would pair this frock with a set of white heels for an ultimate summery color palette.

From the high slit to the cap sleeves, this style has us totally captivated. Don’t be fooled by the high coverage on the front, because there’s a cute cutout on the lower back with a keyhole opening at the top.
