The Weekender Bolero is designed as a second button-on option (in addition to the cape sleeve released with the original dress pattern), but can also be made without buttonholes to wear with any sun dress in your wardrobe. Plus, it's reversible, so you can get two looks in one.
With sleeves and collar all cut in one with the bolero body, this is a super speedy project.
Note: in a departure from my usual cup size range, I've combined A/B and C/D into a single pattern piece. This is do the open front fit of the bolero.
