Cap sleeves can look unflattering, especially when they are extra short and tight. That’s why I’m quick to suggest sleeveless or elbow length as the more flattering option. Or I suggest what I call “diagonal sleeves”, although I have also seen the silhouette referred to as a short dolman sleeve. 

Diagonal sleeves are a mix of a short and a cap sleeve. They’re like an oversized cap sleeve with a much looser fit around the upper arm. The hem of the sleeve creates a long diagonal line across the bicep, which is how it gets its name. The drapey fit and longer length of the diagonal sleeve make it easier to wear than a short tight fitting cap sleeve. The diagonal lines also minimize the size of the bust, especially when the neckline is V-shaped or scooped. Furthermore, the diagonal integrity of the sleeve has a more interesting and structured visual effect than a wide short sleeve, which can look a little frumpy. 

As seen below, diagonal sleeves work with an assortment of necklines and fabrics. Some top styles are more roomy than others, and the sleeves vary in length. Something for everyone. Have you tried diagonal sleeves, and do you find them flattering?
