I have worn a ton of different types of shapewear..from the charcoal type, to the rubber type, and everything in between.  This is by far the most comfortable of all of the varieties I have worn.  I have no problem wearing this all day, as a matter of fact I will not wear jeans without it!!  You have to be careful with all slimming undergarments, and possibly consider going up one size when you purchase (sometimes even down one), you must be mindful of the guides for best fit.  But this one was well worth the money!
