Use age only as a starting point when comparing Lefties and Primark. In kids' clothes, a small difference in waist, sleeve length or rise can decide whether a piece is worn all season or left aside.
| Garment | Lefties | Primark | SIZES tip |
|---|---|---|---|
| T-shirts | Check length and shoulder by fit | Can vary between basics and multipacks | Measure a tee that already fits |
| Trousers | Review waist, rise and length | Adjustable waists change the experience | Do not rely only on elastic |
| Sweatshirts | Can allow room if neck and sleeves work | Check sleeve length and volume | Size up only if hands stay free |
| Dresses | Look at chest, waist and drape | Fabric and cut matter more than age | Check lining and marked waist |
| Coats | Leave space for layers | Check shoulder and sleeve over a jumper | Room should still allow movement |
Why you should not carry one size across
Lefties and Primark sit in a similar space: practical children's clothing, accessible prices and many everyday pieces. Still, every collection can change by pattern, fabric and intended use. A size that works in a T-shirt pack may not work the same way in trousers, a sweatshirt or a dress.
The common mistake is remembering one brand size and applying it to everything. In children's clothing, age on the label helps orient you, but the real body and the exact garment decide. A child may need one size by height in tops and another by waist in trousers.
What to check before buying
Start with the garment most similar to one you already own. For T-shirts, compare chest, shoulders and length. For trousers, waist, rise and leg. For sweatshirts and coats, add sleeve length and room for layers. In dresses, check chest, waist, length and stretch.
If you buy online, open the exact product chart. If you shop in store, look at the real cut: slim, regular, wide, cargo, jogger or oversized. Two garments marked with the same age can be designed for very different silhouettes.
SIZES tip: save a note after trying: “Primark, trousers wide at waist†or “Lefties, T-shirt short in lengthâ€. That note is more useful than remembering age alone.
How much growing room to leave
Useful room allows growth and movement. Excess room makes the garment get in the way, drag, cover hands or slip. In T-shirts and sweatshirts you can allow more volume if neck, shoulders and sleeves still work. In trousers, the margin needs more control because waist, rise and length affect daily comfort.
For coats, test over a layer. If the child cannot lift their arms, there is not enough room. If the shoulder drops too far or the sleeve covers the whole hand, there is too much size. The best purchase is not the one that promises to last longest, but the one that can be worn from now.
How to use SIZES
Save height, waist, chest and brand notes in each child's profile. When a garment works, note size, brand and feel: short, roomy, close, good length, generous waist. Next time you will have a real reference for comparing Lefties, Primark or any other brand.

Final recommendation
If you are between two sizes, decide by the garment's critical area. For T-shirts, shoulder and length. For trousers, waist and rise. For coats, shoulder, sleeve and layers. Lefties and Primark can both work well for kids' basics, but they work best when you buy with measurements, not age alone.
FAQ
Do Lefties and Primark fit the same for kids?
Do not assume so. Always compare the exact product chart and a garment that already fits well.
What should I check first in kids' trousers?
Waist, hips, rise and length. An adjustable waist helps, but it does not fix a clearly oversized garment.
Is it better to buy one size up so it lasts?
Only if shoulders, waist or the critical length still work today. Too much room can make the garment uncomfortable or unused.
