From Capital Chic Patterns:
Cuba Libre is a very loose fitting shirt or shirt dress with a yoke, collar and collar stand, cuffs and cuff plackets, patch pockets and pocket flaps.
View A is intended to be the classic easy fit silk shirt with plenty of volume to offset pencil skirts and narrow fitted trousers. View B is a knee length dress suitable for day wear, keeping the shirt hem for interest. It can be worn with or without a belt for a different look. View C is a dramatic maxi dress, which lends itself to evening wear or summer holiday fabrics.
Note that this pattern does not include a belt - Views B and C are intended to be worn with a purchased belt.
Suitable fabrics are lightweight blouse or dress fabrics, especially thin 'silky' fabrics for View A.
