I purchased this to wear under my dirndl for Oktoberfest and Wurstfest.  I purchased a size large (I wear a 36C bra size, and have some middle-age sagginess) and it fit just about right and gave me nice lift like I have not had in 20 years.  My lederhosen-clad date approved wholeheartedly.  I also wore this for a Halloween event where my magnificently uplifted bust was groped a couple of times by a drunken partier.  I would have liked the straps to be a little bit longer, but overall I am very happy with it.  It washes well on delicate (I hang mine up to dry). Just FYI the back of it is not suitable for dresses with low backs, and you wear it over your bra (it does not have cups--it pushes up on the lower portion of your bra).
