The size chart listed for this item states that a 2X is an 18-20. I am a size 18 but I almost got a 3X because I didn’t want it too tight. So glad I didn’t do that but I should have purchased XL. This item came in a lingerie type box separate from my other items. I was completely shocked when I took it out of the box because it was very apparent that it wasn’t a 2X. On the box it states that a 2X is size 24-26. It shows that a 1X is 20-22. According to the box, the next size down is a L which is 12-14. There isn’t even a size for 16-18. Even though this was a mistake on the company, returns are a nightmare so I will most likely keep it & try to alter it. All the items I ordered were the same size but a couple were too big & a couple were too small. None actually fit me correctly. This is so frustrating! Aside from inaccurate sizing, the quality is decent for the low price.
