This is a tank from American Apparel; so see their sizing chart to get a good idea of what to order. The seller's website doesn't include any sizing info, or the brand of clothing they print on, so I took my best guess and ended up with a product that is far too small--I recommend sizing up 2 sizes from your regular size. Also, since the product was not the correct size, I needed to return it, but neither the seller nor their third party vendor have responded to my requests for a return, it has been a week or more. Buyer beware! I would not order from this company again.
This was a gift for my wife. She loves it; consequently I am happy.
