Baby vest and T-shirt size guide

Wee Belter has three garment ranges: baby vests for 0-18 months, baby T-shirts for 12-24 months and kids’ T-shirts in 3-4Y and 5-6Y. Choose the garment first, then compare the product’s measurements with clothing that already fits.

Which Wee Belter garment covers each age?

Available garment ranges
Garment Size labels Colours
Baby vest 0-3, 3-6, 6-9, 9-12 and 12-18 months Black or white
Baby T-shirt 12-18 and 18-24 months Black or white
Kids’ T-shirt 3-4Y and 5-6Y Black, white or anthracite

How do I compare the measurements?

  1. Choose a vest or T-shirt that fits the child and lay the garment flat.
  2. Measure the width across the chest and the body length in centimetres.
  3. Open the size guide on the Wee Belter product page and compare those measurements.
  4. Select the available size and colour on the product page before adding the garment to your basket.

The age label helps you find the range; the garment measurements help you choose the fit. The size selector on each product page shows the available options.

What is the difference between a baby vest and a baby tee?

A Wee Belter baby vest is a bodysuit with an envelope neckline and three poppers at the legs. A baby tee is a T-shirt. Both ranges include 12-18 months, so choose the garment style as well as the age label. Baby tees also include 18-24 months.

Is there a 2-3Y T-shirt?

There is currently no 2-3Y size in the Wee Belter range. Baby tees finish at 18-24 months and kids’ tees start at 3-4Y. Compare the measurements before choosing a different age label. Contact Wee Belter if you need help choosing a garment.

Choosing a size for a gift

Ask the parent for the child’s current clothing size and, where possible, the measurements of a garment that fits. The Scottish baby gift guide helps you choose a design and garment. The gift pair chooser lets you select a separate size and colour for each garment.
