Which is better for everyday wear?

Pour Femme. It is a versatile floral-amber scent in a large bottle that is easy to replace. Gold Rose Edition is better kept for occasions if you want to preserve a hard-to-find bottle.

Which lasts longer on skin?

Both are eau de parfum, so concentration is comparable. Pour Femme has more owner reports of long wear; Gold Rose Edition has little public feedback to judge by.

Is the Gold Rose Edition worth stepping up to?

Only if you want the limited edition itself. It is smaller, unsealed and harder to find, so the appeal is scarcity, not performance.

Are these the same scent?

No. Gold Rose Edition is a rose-centered limited release. Pour Femme is a separate composition built on mandarin, black currant, rose, jasmine, musk, patchouli and vanilla.

Pour Femme, because it comes in standard retail packaging and is easy to exchange or replace. The Gold Rose box is unsealed and shows marks, which matters if presentation counts.

Is the smaller bottle a problem?

Only for heavy daily use. At 1.7 fl oz the Gold Rose Edition runs out sooner, and replacing it is harder than buying another Pour Femme.

Gold Rose Edition by Michael Kors Women's 50 ml / 1.7 fl oz EDP Spray vs Michael Kors Pour Femme Eau de Parfum

Buy Pour Femme if you want a full-size everyday signature scent with a well-documented floral-amber profile and wide availability. Buy Gold Rose Edition if you want a discontinued-style collector bottle and accept an unsealed box and a smaller 1.7 oz fill. Pour Femme is the safer, more versatile pick; Gold Rose Edition is the rarer one, and its value rests on scarcity rather than on performance.

Choose the Gold Rose Edition if you want a hard-to-find Michael Kors bottle for a collection and don't mind an unsealed box.
Choose the Pour Femme if you want a large, easy-to-replace bottle of a rose-jasmine-amber scent for regular wear.
