It is hard to say because all of their clothes run different. I have bought 4 bras and they are not returnable and way too small, not even close to my size.

It honestly depends on the brand and style. Always check the size chart associated with the item, and view the item objectively. You love it but it has a long waist & you have a short one? It's probably not going to work for you. The size charts have been revised within the past year or so, and some items are definitely junior sizing. You will be able to tell from the charts.

Definitely depends on the brand from them. Some run really large and many run really really small.
