From Alabama Chanin:
The Bolero has long been one of our favorite cover-ups at Alabama Chanin, now joined by the Classic Cardigan. The Bolero works well with any of our sleeveless tops and dresses. Many women who are uncomfortable showing their arms in sleeveless garments gravitate to this piece for coverage. The Bolero can be made in four different sleeve variations or sleeveless. The instructions can be used for either a single- or double-layer garment. The Bolero measures about 11" (28 cm) from the center back to the bottom back edge.
