As far as "one size fits all/most" clothing goes, this bodysuit is pretty cool!  It amazed me how well it fit, but also, how well it seemed to fit other people with very different body types and sizes, according to the reviews and photos that others had posted.
It's also quite comfortable and feels super soft.
In the photos I am wearing a regular bra, but this would definitely look better with a racer/cross back or halter bra.  I also like the fact that it's more of a thing bottom, instead of a regular full coverage bottom.  I'm not a big fan of party lines and this helps a lot with that issue.
Over all I really love it!
