I bought this dress knowing that one size fits all doesnt always apply to bustier and plus size me.  Over the past two years I lost 100 lbs and got pregnant, had a baby, and started working on losing again so size wise I'm kinda in a crap shoot.  I wear a 16/18 in shirts (except they strain A LOT across the breasts) and a 20/22 in pants.

This dress still fits.  Wear a bra or cami with this because the top will pinch a bit if you don't- but it's a pretty dress or cover up and a flattering fabric- unlike the stretchy polyester that drapes on every bit of pudge it's a nice solid cotton and keeps it's form.
