Mommy and me matching shirts look best when they share a design, a colour and a fabric, and let each fit follow the body wearing it. A mother's shirt and a child's shirt are cut for very different bodies, so size each one against its own guide, and if either of you sits between two sizes, take the larger one. In photos the pair still reads as a set, and each of you gets a shirt that actually fits.
What makes mommy and me matching shirts look like a set
A matching outfit sounds like it should mean the same shirt in two sizes. In practice, when you look at a photo of the two of you, your eye goes to the colour and the graphic first, then to how the fabric falls. Fit comes a long way behind, especially since little ones are usually on a hip, in a lap or halfway across the room.
So the sets that work repeat the look and let the cut follow the person. A grown-up oversized tee drops past the shoulder and sits long at the hem. A child needs room for a nappy, a crawl or a climb up the sofa, which changes the proportions completely. Force both shirts into the same shape and one of you usually ends up looking a little off.
COZY's Mothers Day Collection, made with Khwaab, was designed this way. But First Coffee is a white oversized tee for mom. But First Milk is the little one's version, in the same Vanilla Latte White, with lettering that answers hers. There is also Full Time Mom in Midnight Brew Blue, for mothers who would rather wear something darker that still sits happily beside the set.

How to size the mother's shirt
Both mama shirts are cut in a relaxed oversized fit, so the shoulder seam sits past your natural shoulder and there is extra room through the chest and hem. If you have ever wondered whether a relaxed fit is oversized, they are close but not the same: relaxed adds room below the shoulder, and oversized moves the shoulder line itself. Our guide to fit types walks through each one.
The sizing advice on both shirts is simple. Check the size guide, and if you are between two sizes, go up. The shirts come in XS to XL. The model on both product pages is 5 ft 2 and wears an XS, which gives you a feel for how much drape the cut has even in the smallest size.

The easiest check is a tee you already love. Lay it flat, measure across the chest from underarm to underarm, then from the top of the shoulder down to the hem, and hold those numbers up against the size guide. The chest width tells you how roomy it will feel. The length tells you whether it lands at your hip or a little lower.
If you would like to wear it somewhere a bit dressier than a slow weekend morning, our guide to t shirts for ladies from casual to semi-formal has ideas for what to pair it with.
How to size the child's shirt
Kids' sizes work differently, and our kids oversized t-shirt fit guide goes into them in more detail. But First Milk comes in age bands rather than letters, starting at 0-3 months and going up to 4-5 years. Treat the band as a starting point. Two children of the same age can be very different heights, and you know your child better than any chart does.
The product page gives the same advice as the mama shirts: if your child is between two sizes, size up. With children it matters even more. They grow fast, and a shirt that fits perfectly this week can look short by the time you get round to the family photos. One size up in an oversized cut gives a little extra length and room without swamping a small frame. The model on the kids page wears the 1.5-2 years size, if that helps you picture it.

One small tip from the product pages: buy both shirts in the same order. That way they come from the same fabric batch and the whites match. A little variation between cotton batches is normal, and you would notice it most with two white shirts side by side.
Why print and hand stitch embroidery change the match
Every shirt in the collection is screen printed first and then finished with hand stitch embroidery. The print sets down the design, and the embroidery is stitched over it by hand, which gives the lettering a texture you can feel and a depth a flat print cannot match. Because a person finishes each one, no two shirts are exactly alike.

That is Khwaab's part of the story. Khwaab is a brand that works with traditional craftswomen, using handmade techniques to make contemporary clothes. The shirts are COZY's, made in Karachi from 100% Cotton, and the embroidery is done by Khwaab's craftswomen. So the set matches in design, and each piece still carries the hand of the woman who finished it.
Hand embroidery needs a little looking after. Wash the shirts inside out with similar colours, hang them to dry out of direct sun, and iron on the reverse rather than over the print and stitching. No bleach and no tumble dryer. The fabric does not shrink, so the sizes you pick now are the sizes you keep.
What GOTS certified cotton means for a child's shirt
When a shirt goes straight onto a baby's skin, what it is made of matters as much as how it looks. The mama shirts and the kids shirt are all 100% Cotton with no polyester, and the cotton is GOTS certified and ISO certified.
GOTS is the Global Organic Textile Standard. It looks at the whole textile supply chain, not just the raw fibre, and limits the chemicals and dyes that can be used along the way. For a parent, that means a fabric you can trace back, with fewer unknowns touching your child's skin. The dyes are high wash fastness too, so the colour holds through wash after wash instead of bleeding.
Pure cotton also makes sense for summers here, from Karachi's humidity to the heat in Lahore and Islamabad. It breathes, which matters for a little one who cannot tell you their shirt feels sticky. And since both shirts in the set are made from the same fabric, they look the same next to each other in a photo.
This is a limited run with no restocks, so once a size is gone, it is gone. Pick mom's shirt first, size the little one's to match, and shop the Mothers Day Collection.
