Sizes are given as your child’s height in centimetres, and every style has its own measurements table. Her size is chosen by height; the length and chest of the garment are then checked in that table on the product page.
What does the number in a size mean?
The number is a height in centimetres: size 140 describes a child who is 140 cm tall, and size 152 a child of 152 cm. It says nothing about age, so it is her height, not how old she is, that settles the size.
The rule is the same for every kind of outfit: dresses, two-piece sets, jumpsuits and trouser suits. What changes from one kind to another is the set of garment measurements listed next to the size.
Her height is measured once, and the same figure serves for every style. What can differ is how the size is written – a single number or a pair – and the measurements of the garment itself. Sisters are no exception: each girl takes the size that matches her own height, even when their outfits are meant to go together.
How do I measure her height?
Height is the one measurement that holds good for every table in the shop: each table gives it in the first column, as the size. Measuring therefore starts with height, and all it takes is a flat wall, a book, a pencil and a tape measure.
- Ask her to take her shoes off and stand with her back to the wall, heels touching it.
- She should stand tall and look straight ahead, with her head level.
- Lay a book flat on top of her head, pushed back against the wall, and mark the wall along its lower edge.
- Measure from the floor to the mark and write the result down in centimetres.
It is easier with two people: one makes sure she stands straight, the other places the book and marks the wall. The best moment to measure is just before you order – children grow, and a figure taken a few months earlier may no longer match her height. If the result lands on the border between two sizes, measure again, then apply the rule set out below.
Size 140 or size 140/146 – what is the difference?
Sizes in the shop are written in one of two ways. On the single scale, each size is one number – 134, 140 or 146, for instance – and neighbouring sizes are 6 cm of height apart.
On the paired scale, one size joins two neighbouring sizes from the single scale: size 140/146 covers the heights described by sizes 140 and 146. Each size therefore covers a range of heights rather than a single figure: on the paired scale the range shows in the size itself, and on the single scale it is marked out by the neighbouring sizes. The table below sets the two scales side by side.
| Size on the paired scale | Single-scale sizes it covers |
|---|---|
| 104/110 | 104 and 110 |
| 116/122 | 116 and 122 |
| 128/134 | 128 and 134 |
| 140/146 | 140 and 146 |
| 152/158 | 152 and 158 |
| 164/170 | 164 and 170 |
A style’s scale is shown in the size selector on its product page and in the first column of its measurements table. A girl who wears size 146 can therefore also choose from styles sized 140/146.
Occasionally a style mixes both, with sizes such as 134 and 140/146 on the same scale; the rule for choosing stays the same. Scales also end at different points – some at size 158, others at 164 or 164/170 – so it is worth checking the range of a particular style in the size selector on its product page.
What if her height falls between two sizes?
Between two sizes, height decides: once her height is past the range of one size, the next size up is the answer. The ranges are set by the sizes in the first column of the chosen style’s table, and figures from another chart do not carry over.
On the single scale, a height past size 134 means size 140. On the paired scale, a height past 140/146 means 152/158.
Garment measurements do not carry over from one style to another either. The length or chest of the same size may differ from style to style, so the figures are always read in the table of the style that is going into the bag.
How do I read the measurements table?
Every product page carries the table in its Size and fit section. The first column gives the size – her height in centimetres – and the other columns give the garment’s measurements for each size, also in centimetres. The tables give no ages: the size is chosen by height.
- Find the size in the first column that covers her height.
- Read along the same row for the other measurements, such as the length of the outfit or the chest.
- If the product page suggests checking one more measurement, take it and compare it with the figure in that row.
Chest is measured with the tape running level round the fullest part of the chest; for a measurement under the arms, the tape sits just below the armpits. The tape should lie flat without pulling tight, and a thin T-shirt is the easiest thing to measure over.
Where do I find the cut and fit of a style?
Above the measurements table, in the Size and fit section, one or two sentences explain how to choose the size of that particular style. For some styles they also name the cut – straight, fitted or flared, for example – and for a fitted cut they sometimes point to a measurement worth comparing with the table. Whatever the cut, the size is still chosen by height.
Which measurements does each kind of outfit list?
The measurements depend on the kind of outfit and on the style. The table below sums up what the tables on the product pages for dresses, jumpsuits, two-piece sets and trouser suits contain.
| Outfit | Measurements in the style’s table, besides size |
|---|---|
| Dress | length or total length; chest, or chest under the arms; sleeve length on some styles |
| Jumpsuit | total length; inside leg, and on some styles leg length from the waist; chest and waist |
| Two-piece set | chest; sleeve length; length of both pieces – jacket and trousers, or top and shorts; waist |
| Trouser suit | jacket and trouser length; chest; sleeve length from the underarm |
If the measurement you need is not in a style’s table, write to sklep@mymaluna.pl and give the name of the style from its product page.
How do I choose the size, step by step?
In short, the whole choice comes down to four steps.
- Measure her height without shoes and note it in centimetres.
- On the product page, check which scale the style uses: single or paired.
- Choose the size whose range covers her height; if her height is past that range, take the next size up.
- Read the garment’s length and chest in the same row of the table.
Questions and answers
Is the size chosen by age?
No. Sizes are given as your child’s height in centimetres, so her height decides, not her age.
What does a size written as two numbers, such as 128/134, mean?
It is a size on the paired scale, joining two neighbouring single sizes: 128 and 134. Both numbers are heights in centimetres.
What if she is between two sizes?
Between two sizes, height decides: once her height is past the range of one size, the next size up is the answer. The ranges are set by the sizes in the style’s measurements table.
Do one style’s measurements apply to another?
No – every style has its own table, and the length or chest of the same size may differ between styles. Only her height stays the same.
When is the best time to measure her?
Just before you order. Children grow, so a measurement from a few months back may already be out of date.
