This plum HHH Athena was worn once to see “Hamilton” (…and Peggy!). She’s thick but still very soft and comfy. Because of her thickness I was able to go without a bra (38D) and didn’t feel floppy or without complete support. The dress form is a size US 10 / 36C for size reference but there’s plenty of give remaining. I have this same fabric in and Ellie and she’s a M. Non-smoking // 10lb pup friendly home
