Hello and welcome!!
I don't know what will set you off, as I have allergies to some strange things and get set off by weird things, but I have a few that are worth trying maybe?
Flower Bomb by Viktor and Rolf - It is a sweet, light, warm scent that really captures female beauty in a fragrance. I don't think it will be hard on your allergies.
If you want to stay away from the stores then you should order samples from online stores, or other basenoters. Good luck on your hunt. I know it's hard...
