This fashion magazine page from the early 1930's plays up some great ways to use buttons. The slinky, slender silhouette of that era looks great with the sleeve variations shown here, some sporting button accents. Neckline and shoulder yokes, sleeve cuffs, pockets and shoulder straps have buttons as well.
Part of what makes the look so elegant is the accessories. Their gauntlet gloves really have great style. And it would be hard to miss those jaunty little hats worn at an angle over the forehead with a bit of finger waved hairstyle peeking below.
