I think kabuki sleeves can be very pretty and flattering, and other are not as flattering. I personally love lose-fitting and flowing sleeves. I am actually medium-sized, but I absolutely do not like when clothes are tight in the arm, it feels very restrictive and uncomfortable.
I love kabuki sleeves that go either to the elbow or above the elbow. I think unless you have long arms, this makes your arms look really short and stumpy.
I love the flowing, silky type kabuki sleeves. They look so elegant and fashionable. I especially love when the kabuki sleeves are loose and flowing, and the rest of the shirt is fairly tight and form-fitting.
There are also quite a few kabuki sleeves on sweater shirts that make them more unique and fashionable. I at least have to have one sweater shirt with kabuki sleeves to wear all fall long. They even look good with a tight long-sleeve shirt underneath. Kabuki sleeves are so much more comfortable and easy to move in that regular sleeves are.
