short sleeved or a vest?

Is there a difference between a cardigan with extremely short sleeves and a vest? Vest seems a bit unfashionable at the moment, so I go for short sleeved. I loved to knit this project - easy enough to knit in front of television, but still there's something special.

This might be the first self made cardi/vest I really love to wear. The yarn is great too, warm enough even for colder days. I didn't follow the pattern this time either, but who does?

Pattern: 105-9 jacket with lace pattern and raglan sleeve by DROPS design
