NYC entrepreneur’s inflation-era side hustle suddenly a seven-figure business — creating chic diaper bags for trendy UES moms

When it comes to parenting style, Alexandra Rutkay’s got it in the bag. 

Unwilling to forgo fab fashions for frumpy mommy gear, the Upper East Sider dreamed up a designer diaper carrier that’s now affording her the life of her dreams. 

“We just made seven figures,” Rutkay, 41, married mom and founder of posh baby bag brand Citymouse, told The Post. 

Rutkay and husband David, who recently left his six-figure job in luxury car sales to serve as Citymouse’s operations manager, run their literal mom-and-pop shop from their two-bedroom uptown abode. 

The couple pay themselves around 18% of the overall profits — reinvesting the rest back into the biz. They’ve sold more than 10,000 bags this year alone.

“We do everything from our apartment,” said Rutkay, who doubles as a makeup artist for “Law & Order: SVU” star Mariska Hargitay.
