i've seen this term around - hollywood regency - but i let it slip past me. up until wednesday i let it be seen, but never registered. up until wednesday i had not heard of the parker palm springs. this leads to fantasizing about sun, living in southern california, having bold wallpaper & wearing a bathing suit with a flowy white robe all day, every day.
hatch has a great post on decorating titled hollywood regency 101 that you must read if you are interested in the style. it's funny to look back at my apartment inspiration folder & see how much of it is in this style.
