SpeedoWomen's Swimsuit One Piece Prolt Super Pro Solid Adult

Is if padded ?

How the heck do these sizes work?? For reference, i am 5"6, around 150lbs, but athletic. Typically wear size 6 bottom, size 4/small tops

Im 5'9 130 lbs 36dd chest, what size do u recommend..being im tall

How do i go about returning the suit? i just got it today. even though i read the reviews and sized myself correctly, it was way too small.
