CosabellaWomen's Dolce Soft Bralet

The sizing chart from Amazon doesn't convert to petite, small, medium... Will a petite be the correct size for a 32A?

Would someone who is a 38 b be be able to wear this? would the large be too big for a b cup?

What does "petite" mean in comparison to "small?"

Is there any padding? Does this give you any shape?
