A recently proposed acquisition between two intimate apparel companies has one investor up in arms.

On July 24, Maidenform Brands Inc. announced that HanesBrands Inc. would buy it for $23.50 a share, or about $575 million. The all-cash deal is subject to approval by Maidenform shareholders and regulators; it's expected to close in the fourth quarter of this year.

But one investor thinks Maidenform is worth more than $575 million. In a complaint made public yesterday, a Maidenform shareholder is suing the company for agreeing to a merger that is “grossly unfair” and that “does not reflect the intrinsic value of the company as a takeover candidate.”
