Their large size clothing is cut weird like Wedding and Formal dresses in those stores getting a customer to "have to make alterations". I ordered TWO one piece with a skirt swimsuits and they bottoms fit but I couldn't get the body of the suit up over my torso. My friends even tried to put on the suit and the same thing happened. It is like they use scrap garment pieces and just sew them together to make one sell-able garment.

Always order 3X or above if you are size 26. Size 1X fits great for 18 - 2 / 2X = 22 - 24. Love their clothe, but always err on the side of caution and order the bigger size.

It will depend on the designer. Full Beauty offers clothing from a variety of vendors. I only ordered one thing from them and found it to run large. My experience will not be a good way to base your decision. A safer bet would be to read the reviews on each clothing item. I noticed many items had at least a few reviews.
