I went a size larger due to the fact that I have read on so many other Patty shirts that they run small. Well, they don't. They are made to hug your figure and are made of amazing quality. These shirts are not made to hide lumps, they are made to accentuate what you have. they are very flattering and insanely comfortable. I can't say enough how I love the long sleeves and long mid section that actually hides your skin with low rise jeans. The material of this shirt is very thin and breathable while staying soft and comfortable. It's stretchy fabric makes it easy to put on and comfortable to wear.
