One Hour Dress and matching slip dress
If you're into vintage fashion, you've probably heard about the one hour dress. It was a simple style of dress that was popular back in the 1920's. While they rarely only take one hour to make, they're beginner-friendly and highly customisable thanks due to their simple shapes.
The one hour dress is a simple dress that's usually made out of a woven fabric. It's nice and loose, which means it doesn't need any fasteners.
The top part is a simple T-shape while the bottom is a wide rectangle, extending far beyond the top's margins. This extra fabric would be gathered and sewn into a cut inside of the main dress to create room for the hips.
If you'd like to find out how to make these, check out these tutorials by The Closet Historian, Festive Attyre and The Vintage Dancer. They'll show you how to draft a pattern according to your own measurements, and how to put the dress together.
Check out this original 1920's drafting guide by Mary Brooks Picken to see how it was originally done.

Sometimes, one hour dresses were made from sheer materials to create different effects depending on what slip dress was worn underneath them.
These slip dresses are even easier to make than a one hour dress. The principle's the same, but the top's a rectangle instead of a T-shape with sleeves. Check out this tutorial by Sew Historically to find out how to make your own 1920's slip dress. This tutorial by American Duchess shows you how to make a version without the gathered hips.
You can easily turn these slip dresses into a playsuit by adding a rectangle at the crotch, turning the skirt part into shorts. Check out my 1920's playsuit project to see an example.

This type of dress is a lot of fun if you're looking for an easy, highly customisable project. Add whatever trims you want, mess around with the neckline, make a sleeveless version or one with longer sleeves, turn it into a mini- or maxi-dress,... There's plenty of options.
