Guerlain gives Isetan Shinjuku a two-day head start on its new Règle Bleue fragrance
Guerlain is letting Isetan Shinjuku sell its new Règle Bleue fragrance two days before anyone else can buy it nationwide, backed by two scents the pop-up alone will carry — a reminder that a fragrance launch's first week in Japan is often choreographed by a single department-store floor as much as by the brand.

Guerlain is giving shoppers at Isetan Shinjuku a two-day jump on its new fragrance Règle Bleue, opening a pre-launch pop-up on 26 August, ahead of the 28 August nationwide release, the beauty house said in a statement carried on PR TIMES.
