This mother-in-law means business.

*Hailey received an eyebrow-raising gift from her soon-to-be mother-in-law but it’s the reasoning behind it that left her gobsmacked.

Hailey was thrown a surprise lingerie hen party by her mother-in-law who then gifted her a lingerie set she wore on her wedding night in hopes that it would make her more fertile, The Sun reports.

Taking to Reddit, the bride-to-be anonymously shared that her mother-in-law had repurposed one of her own night-gowns specifically from her wedding night.

While Hailey recalled the grim experience, this was the last thing she expected from her mother-in-law whom she described as someone with “a lot of family heirlooms and antiquities, so I assumed it would be some hair broach, or a garter or something”.

But to her surprise, it was something that caught her completely off-guard.

“It was a hand-me-down nightgown that she wore on her wedding night for me to wear on my wedding night,” she penned.

“She then made a “joke” about fertility and how she got pregnant “very soon” after the wedding. Isn't that weird?!”

Well, now that’s one way of giving your daughter-in-law something borrowed.

*Not her real name
