Ultimate Wireless Bras are Heaven!

I originally bought one of these bras to wear at home thinking it would not be something I could wear in public. That soon changed as I realized how comfortable AND supportive they are with excellent coverage! The last time I put on a "real" bra, I could not keep it on for even 5 minutes as it was so uncomfortable! Katie Em bras are awesome!

Kimberley, this is exactly why we love Katie Em bras too — total comfort without compromising support! We're so glad they've become your everyday go-to (and that “real” bras are officially on notice!). Thanks for the kind words!

Amazing store and products.

My PJ place for sure! I have been in a couple of the stores and the girls are all so friendly and helpful with finding the right size and product. Once you know your size it is easy to order on line as everything then fits true to size. I recently lost weight so was unsure of my size. Two big thumbs up and I love the bamboo moisture wicking at my age!

Thank you

Thoroughly enjoying the chain link necklace. The earrings aren’t among my favourites but ok. The popcorn & salted caramels will be enjoyed over the holidays…
Briefs are a bit higher than expected but nice fabric.

Katie em wireless bra

My decision to purchase this bra online was pending due to uncertainty of fit.
When it became available during a bogo sale event I couldnt refuse. I purchased 1 nude shade and 1 black.
I was looking for minimal detailing which I would be comfortable wearing during heat waves during the summer months.
This bra offers exactly that. It is lightweight, soft material, no irritation from itchy tags, clasps, or shoulder strap adjustments. There is no sweating beneath bustline/ribcage which I sometimes experience.

The foam cups I removed after 2 days of wearing as I didnt like the look of 2 unnatural circulars. They reminded me of breastfeeding pads so I removed them. I think a teardrop shape would have been better. The bra is totally fine without the cups, they can be easily removed through a small opening slit. The polyamide material acts like a compression against my chest, so it does flatten. Be mindful of this if you are less endowed. I find the appearance less flattering than that of a regular push up. Perhaps this may be well suited for a fitness class or other activity. Overall I am very pleased with this product. I will continue to wear this purchase in comfort.

Hi Laura,

I am so glad that you are enjoying the bras! Thank you for the great feedback! I hope it kept you cool in the warm weather!

Stay Cozy,

Best Bra Ever!

This is one of the most comfortable bras that I own! The soft fabric feels so nice on, and washes beautifully! It is clear that it was designed to fit and flatter everyone. I like that you can easily remove the inner cups or keep them in as they do provide really nice shape. A must have in your closet!
