Light blue New Balance sports bra

The only issue is the stain on the inside but I have never worn it so I genuinely could not tell you what it is from but I have scrubbed it with everything I could think of to lift the stain and it wouldn’t come out but luckily it is on the inside and with the number of times I have washed it trying to get the stain out that it’s definitely clean/disinfected(?) But the bra does have built in padding and is VERY supportive.
