Puff Sleeve difficult to answer how the design was chosen so that the upper body will not look too sturdy? ● select the wide or low-neck collar design can look so bulky Puff will not be too bloated. ● wider at the top of the mix to make body look slender, so I chose to clean lines with Puff jacket trousers or skirt wise.
