White no-wire bra size XL see description

White no-wire bra tag says XL but I normally wear a 34 C and the sides were bowing. I took the measurements which were approximately 26" perimeter and cup was approximately 6.75" which I think /believe is a C cup. Per Google the size is estimated to be 30 or 32 C . Washed in cold water and lined dry. Bra has adjustable straps
