How does the Undercover Mama attach?

You attach Undercover Mama shirts to the outer flap of a top-opening nursing bra by sliding each hook onto the flap a little below the clasp. Usually it will slide on just below the seam where the bottom of the clasp is sewn to the bra. You want to push enough material into the hook so it is snug. On most bras you can slide the hook clear on so that the entire width is inside the hook, but even if the strap is too wide to fit completely in, it still works just fine. You can also slip the hook of the Undercover Mama on to the strap of your bra instead of the flap. Keep in mind with this option you will need to unhook the Undercover Mama each time you nurse.

What material are the shirts made from?

Undercover Mama shirts are made out of quality fabric that is soft and stretchy for coverage, support and durability. 95% cotton and 5% Spandex.

How do you wash them?

You machine wash them in cold water, no bleach, and lay flat to dry.

What if I am between sizes?

Undercover Mama shirts work best when snug fitting, so if you are in between sizes go with the smaller size. General suggestion is to go a size smaller than your regular shirt size.

Can I use my Undercover Mama if nursing doesn't work out for me or after I'm done?

You can use the Undercover Mama with a regular bra, see option 2 image above. Many moms tell us that they love their Undercover Mama so much that they wear it long after they are done nursing!
