This has got to be one of the MOST accurate sizings from a none-name brand on Amazon. I ordered both a size XXL and a size XXXL and both fit, even over my 50-something-inch-hips! I am 5'9" and this hoodie covered my entire bum, which is what I wanted. Dare I say, the 3xl was a little too big LOL. I wanted baggy but the 3xl looked too big (covered all my curves) yet the 2xl was a "perfect" fit on my hips (more snug / less loose on hips).The chest area was super loose, so I would say their provided chest measurements are accurate. However, the size 2xl, I felt a little tighter in the underarm area (but it wasn't uncomfortable). I would order your size according to a Hanes or FruitOfLoom sweatshirt in MENS. So If you are like a loose size 2XL in a Hane's Men's Sweatshirt, I would order a size 2xl to wear as a dress or a size 3xl to wear as a ridiculously big onesie lol.CON: My only issue would be the hoodie not being "cute." The hoodie is too short on and I wish that was a little bigger and as loose as this hoodie overall. The hoodie does work it just doesn't look cover over your forehead, stops behind the hairline. More than likely, I probably would wear with the hood down/off as it looks better that way.Overall, I would recommend this to someone who wants something cozy for loungewear or to dress up with boots. It would be okay with yoga pants and jeans, but I think it would look too bulky without exposed legs or tight leggings. But hey, if you want a hoodie to hide everything this one is definitely it. It's a decent price for the quality (like Hanes) and the long-length. I would recommend and may reorder in a tighter size (to show off my curves), I hope this helps :)
