Every stitch of the Cosari HeartRib Lounge Set is designed to eliminate the pinching, overheating, and laundry stress of traditional pajamas.
Our 220 GSM vertical micro-ribbed knit stretches up to 35% horizontally across the bust and hips, recovering instantly so your shorts never bag out by morning.
Finished with dense crimson-red overlock stitching along the cropped cami hem and both short leg openings for a romantic, wavy ripple that never frays.
Weighing just 185 grams total, the open-channel ribbed knit and sleeveless scoop-neck cut vent trapped body heat under heavy duvets—zero sweaty satin cling.
Skip the delicate hand-wash sink routines. Colorfast yarn and print technology keep the white ribs crisp and the red hearts bright in a standard 30°C cold wash.
The scoop-neck cropped camisole meets the top of the matching high-waisted shorts right at your natural waist—giving you a flattering, intentional look for morning coffee runs and weekend houseguests.
A 2.5 cm fully encased elastic waistband stretches smoothly over your hips and lies flat against your stomach, preventing the painful twisting and digging of non-stretch woven shorts.
Thin fixed fabric spaghetti straps use the natural give of the rib knit instead of hard plastic or metal adjuster sliders—so nothing digs into your shoulder blades when you sleep on your side.

I wear this white ribbed heart-print cami and shorts set around the house in the morning. They make me feel like my life is put together, like I am a functioning human in society who can order as many lattes as she wants.
I wish it were socially acceptable to wear these out and about—they're truly that cozy. The ribbed knit has a nice stretch, and the red lettuce-edge trim on the cropped cami and shorts is such a cute touch.
I have several pajama sets, and this cami and shorts combo is one I keep reaching for. They are super soft and wash up really well. The little red hearts have stayed bright, too.
Soft, stretchy, and good quality material. The ribbed knit feels nice against my skin, and the elastic-waist shorts are comfortable enough that I don't think about them while I'm sleeping.
I love the cute design on these! The scattered red hearts are adorable, and the red lettuce-edge ruffled hems on both the scoop-neck cami and shorts make the whole set feel extra sweet. I'd buy it again.
The fabric and the comfort is great with these pj's! The sleeveless spaghetti-strap top and shorts feel breathable when i sleep, which is nice when our bedroom gets warm. i would definitely buy another set!
i love these pajamas and would recommend them to my family. The elastic waistband is stretchy and doesn't feel tight, and the little red heart pattern is so cute for lounging around at home.
The perfect pair of ribbed cami and shorts PJs for warm sleepers and summer lounging. I run hot at night, and this lightweight set is comfortable for sleeping and hanging out the next morning.
Tencel stresses me out, because it should be washed separately on gentle and I'm too lazy to do that, especially for pjs. This ribbed-knit heart set has been much easier for me—I put it in a regular cold wash without fuss.
I hate spending a lot on pajamas that turn out to be super stiff crunchy cotton. This ribbed-knit cami and shorts set felt soft, stretchy, and forgiving right out of the package. Much more comfortable for lounging.

No—the thin spaghetti straps are crafted from soft, fixed ribbed fabric with natural mechanical stretch. We eliminated plastic and metal strap adjusters on purpose so nothing digs into your shoulder blades when you sleep on your side or back.
The camisole features a flattering modern crop that hits right at the natural waist, meeting the top of the elastic-waist shorts with just a hint of midriff movement when you stretch or lounge.
No. Both the scattered crimson-red heart print and the dense red lettuce-edge overlock stitching are colorfast in cold water. In our 5-cycle 30°C (86°F) cold wash tests, zero pigment bled onto the white ribbed background.
The 220 GSM vertical ribbed-knit texture provides comfortable everyday coverage that is noticeably more substantial than flimsy jersey tees. However, because the base fabric is bright white, dark or neon undergarments may show faintly—we recommend nude underthings when wearing it around houseguests.
When washed in cold water and air-dried or tumbled on low heat, shrinkage is under 2%. Avoid high dryer heat, which can shorten vertical rib-knit fibers and fixed spaghetti straps.
