Size 8 ladies Lululemon swiftly tech tank in gray, almost white. There is a spot marked on the front that I spot treated, washed & air dried. You might be able to try again & get it out but I want to be very transparent. Top is still wearable as is but maybe for grunge work or painting, dog washing, etc. my bet is that with a little elbow grease, the spot will come out. No idea what it is.
