Ravijour (JP only) is a sexier and more provocative line than Peach John. The ads are racier and their theme is all about being sexy. They often get their ideas from Victoria Secret ads and also have collaborations with the Kitson brand which is very popular in the US. Their concept is all about being a woman and feeling sensual in their own skin.
My suggestions from their webstore:
Love Line: romantic line, ruffles and lace
ROOMY: comfy and lounge wear
STEADY: playful and colorful
Ravijour Honey: casual clothing line including leggings
Over the twelve: very casual and playful tank tops and shorts
Bunny Line: pastel colors
