How To Be Mamma Mia's Donna & The Dynamos For Halloween

My colleague Kathryn Lindsay is convinced that Mamma Mia is the Rocky Horror Picture Show of our times. One day, in the not so far off future, flocks of Mamma Mia fans will gather for special screenings of the movie wearing overalls.
But we're not there — at least, not yet. Mamma Mia! Here We Go Again is still in theaters, and it'll be a few years before the process that converts a normal movie into a cult classic can begin. In the meantime, we can show our commitment to the Mamma Mia fandom on Halloween. Channel your inner Donna, your inner Rosie, and your inner Christine Baranski — err, Tanya.
What's required for a Donna and the Dynamos costume? It's easy. Flared pants, halter tops, and total and complete earnestness. When you walk down the street in your Donna Sheridan outfit, we want you to sing ABBA like you mean it. Grab two of your friends and don these duds for a dynamite Donna and the Dynamos Halloween look.

The Pants

Bellbottom pants are arguably the most important component of a Donna and the Dynamos costume. They can made of denim or shiny cotton-polyester blend, so long as they are high-waisted bellbottoms. This Etsy seller has the exact three-tiered ruffle pants that Donna and her friends wear in Mamma Mia! Here We Go Again. The Dynamos might veer away from black pants in the movie, but you could definitely wear these black ruffled bell bottoms again.

The Shirt

Go for maximum color. This shiny halter top or this sequin tank will provide necessary pop. Alternatively, if you want ruffled sleeves, this tied top will certainly do the trick, and it comes in many colors.

The Belt

In Mamma Mia! Here We Go Again, the Dynamos cinch their tops with thick swaths of golden fabric. Weirdly, satin bridal sashes work really well for this.

The Jacket

You have a few options. You can go for denim vests like Donna, Rosie, and Tanya do in Mamma Mia! Here We Go Again. Or, you can load up on the sparkle. People will get the idea.

The Microphone

Without this giant glitter microphone, people will just think you're time travelers from the '70s. This way, they'll know you're Donna and the Dynamos.

Platform Shoes

Find '70s-inspired platform heels or tall gogo boots, depending on whether you wear pants or shorts.
