Khloé Kardashian has kept her style chic, low key and primarily black throughout her pregnancy — and her official announcement fit right in.
The Keeping Up with the Kardashians star, 33, confirmed on Dec. 20 that she is expecting her first child with boyfriend Tristan Thompson. Kardashian shared a photo of herself and Thompson, 26, in which she is sporting a black Calvin Klein bra with a white bottom band.
“My greatest dream realized,” Kardashian captioned the snap, where both her own hands and Thompson’s are wrapped around her stomach. “We are having a baby! I had been waiting and wondering but God had a plan all along. He knew what He was doing. I simply had to trust in Him and be patient.”
The bra the mom-to-be wore in the beautiful black-and-white photo is the brand’s Modern Cotton Collection Cotton Blend Racerback Bralette in Black, which is available for $28 at Nordstrom.

“I still at times can’t believe that our love created life! Tristan, thank you for loving me the way that you do! Thank you for treating me like a Queen! Thank you for making me feel beautiful at all stages!” she continued in her sweet Instagram post.
“Tristan, most of all, Thank you for making me a MOMMY!!!” Kardashian added. “You have made this experience even more magical than I could have envisioned! I will never forget how wonderful you’ve been to me during this time! Thank you for making me so happy my love!”

Over the months leading up to her announcement, the Revenge Body star has been snapped a few times out and about in a variety of loose-fitting garments — primarily in dark colors — but has often been keeping to herself.
“Khloé is ecstatic about being pregnant,” a source previously told PEOPLE. “She has been fine with being out of the spotlight. It’s like she realized that she needed a break. The baby is a huge blessing in many ways.”
Added the source, “She wants to give birth in Los Angeles, so her family can be around,” noting that Kardashian “still has a couple of months to go” before welcoming her son.
