This silk lingerie set from Amazon is available in sizes 16 Plus-24 Plus. It is $22 and comes in 5 colors. I ordered it in size 16 Plus. This runs so, so small. I need at least an 18 or truly probably more comfy in a 20. This is a great option for someone who wants to feel sexy but have a bit more coverage on the legs and tummy. I would totally sleep in this set, too.
