Nahema by Guerlain?

You can only buy that one at the Boutique.

I wear the parfum in the summer... it's a lovely peachy-rose scent for warm weather. I can't wear it in cold weather.
 
^^ No, I think it may be more expensive, not sure.

I could only buy the large size in the pure parfum because they don't make the smaller sizes any more and I think it was somewhere between $250 and $295. This was a few years ago.

They make smaller sizes in the EdT of course - the EdT is always reasonable but all Guerlains smell best in the parfum concentrate.

The Boutique has testers in the parfum, if you need to test it first.
