The original poster was certain a co-worker would say something if they liked or disliked it. The possibilities that first come to mind are:
1.) They have higher priorities on their mind. Solution: look for the lull in work before expecting anything.
2.) Apply more or apply just before being around others.
3.) Maybe the fragrances aren't working for you positively OR negatively. Try something else.
Try not to offend the most, but always please yourself.
