Style Secret: Bold PatternPattern helps to embellish the Hollywood Regency setting. Trellis and animal prints, Art deco and neoclassical motifs, wide stripes and geometrics all are on point, as is black and white harlequin flooring. Leave the timid florals and mannerly plaids to another style; this one requires a more emphatic approach.Behind the scenes: Wallpaper is back in vogue, and Hollywood Regency practically begs for it. Now's your chance to work in a showy print or splurge on a hand-painted mural-style design. If you worry that a whole room will be overkill, try papering just an accent wall or the ceiling, or set off an oversize panel with a gilt frame.
