In brief: RASH IN ARMPITS

Without seeing the rash, it's difficult to make an accurate diagnosis.
This sounds like a rash due to either a new sweater or blouse, or an underarm deodorant or a new soap, or new laundry detergent. Warm water compresses, a mild cleanser like cetaphil, and an over-the-counter Hydrocortisone cream, twice daily might giver some relief. If no better, have her examined by a dermatologist.
