Both weather and a cold can change how a perfume smells on you. Don't get rid of them...wait til the time of year you liked it before and it will all come back to you.
That's good advice melitalee, , I'm always inclined to ditch and move on as the seasons change, and only have a few in my wardrobe, tending to be devoted to one, and use up and finish. It's funny to notice habits. I think I must fall into the 'looking for a signature scent' type.
Perfume and memory is very strong, Omnia Crystalline I now associate with recent illness, , and I wonder if you can shift that recollection, even if time passes, say to next year? I've been careful to do minimal testing straight after the illness, because everything seems so intense.
The only perfume I have even had a major U-turn on is Jimmy Choo. It changed from total infatuation for a few weeks, to a total sudden grinding halt, out of the blue, like I just can't wear this. Maybe it was the heat or something at the time. The irony is it's the only one, that my hubby has ever commented on, ummmm, "quite like that", which is a major response for him, lol. I think I will see, if time will change my attitude again on this one...
