This was created to fill the void where either you wish to cover your arms in a sundress - or it's just too chilly to wing a sleeveless top. The pattern has every colour you could need for a great layer, and if it's not a dress you want it to go over, then it looks just great with jeans, shorts and skirts. Quite the piece!
It is quite small, and a difficult one to measure corrently due to it not closing or covering the bust. So, the general sizing would be more like Small (size 8), Medium (size 10), Large (size 12). Just watch the top of the arms - circumference for Small 32cm, Medium, 34cm and Large 36cm.
