How to sew children’s tank top:

You can find sewing instructions here: How to sew children’s tank top / undershirt

You can also find inspiration in this article: How to sew women’s tank top ROSES 

Note: you don’t have to cut off seam allowances for bias tape hems when sewing children’s version.


You can sew this tank top on an overlock or a regular sewing machine. Before you start sewing, I recommend reading this article:

  • Use thin / medium knits – elastic fabrics – (ideally cotton knit with elastane etc.).

Required amount of material:

(120 and 140 cm wide fabric)

  • sizes 80 – 122: 60 cm
  • sizes 128 – 164: 80 cm

There are two versions of this pattern:

(you will receive both of them after purchase):

  • 1st version (one size view) – PDF A4 – pattern in individual sizes with seam allowances outlined – all individual sizes of the pattern (pattern of each size shows sewing lines and seam allowances are outlined too).
  • 2nd version (classic view) – PDF A4 pattern showing all sizes without seam allowances – all sizes are outlined “in one picture” (each in its own color) without seam allowances.
    • You can choose what works best for you. The advantage of the classic view (where all the sizes are shown) is that you can easily customize your pattern to fit body types in between the chart sizes. One size view saves time during preparation – you do not have to think where and how much to add for the seams, because everything is already there.

For best results, please read the following:

  • The patterns are constructed in ready-made sizes, because it is not possible to construct a pattern for all body types (the size chart would get too congested).
  • To make the clothes fit the individual figure perfectly, you need to carefully measure it first. Then compare measurements with size chart, and paper pattern. That is the only way to find best pattern size.
  • In addition, it’s almost always necessary to adjust the pattern slightlyto make it fit perfectly. (Even if we have two women whose measurements are the same, they will differ in other ways – one of them may have a narrower back and a larger bust, the other may be more muscular with smaller bust. One of them may also have wider hips and flatter buttocks, the other may have narrower hips and rounder buttocks…) Patterns (and their sizes) are only rough guidelines. If you are going for perfect fit, you need to perform fitting tests and adjust the garments accordingly. Sewing is a creative activity and you need to take into account that each of us is built differently. THIS APPLIES TO CHILDREN’S AND MEN’S CLOTHES TOO – WE ARE ALL UNIQUE.
  • If you are using some pattern for the first time, always sew “test sample” from a cheaper fabric first. Mark any adjustments in the paper pattern and then use it to sew the final product. It is a classic tailoring method. No two fabrics are the same, therefore, please note that what works with one fabric may not work with another. That is why you should always sew test samples. Sewing is not like baking, you can’t just pick the pattern and expect the perfect results without some measuring, testing and adjusting. That’s just how it works.
  • I also recommend temporarily stitching all seams that affect circumferences (such as side seams, instep seams, etc.) before sewing. So, you can try the garment on and adjust it if necessary. Do not underestimate ironing and testing the clothes during the sewing process.
  • Also don’t forget to carefully mark seam allowances. Beginners often forget about them. It is necessary to measure seam allowanceswith the measuring tape around the entire pattern and then sew along the correct sewing lines – seam allowances width away from the cutting edges. Careless work with the seam allowances can result in large deviations in the overall widths and lengths of the individual pieces.
  • When positioning the paper pattern pieces always make sure that the pieces are oriented correctly.
