Filles

A kilted skirt or a tartan dress, a plain blouse, and a sash pinned at the shoulder for the most formal events. Plain shoes and socks or tights below. Everything else stays solid so the tartan is the only pattern in the outfit.

The same shoulder and the same pinning method, though usually a narrower sash sized to the child. Pin through both the sash and the dress so the weight is carried properly. See tartan sashes for how the convention works.

Measurements. Age based clothing sizes are averages and children vary widely, so ordering to age six will fit some six year olds and not others. Waist and finished length are the two numbers that matter for a skirt, plus bust for a dress.

Yes, and for most occasions it is the more practical choice, since a skirt with a plain blouse can be reworn in different combinations while a dress cannot. See flower girl dresses if the occasion is a wedding with a set outfit.

Cool hand wash or a gentle machine cycle inside out, then hang to dry. Press the pleats individually on a low setting through a cloth. Acrylic is a genuine advantage here, since it survives washing where heavier traditional cloth would need professional cleaning.

From around three or four, once the garment can be properly proportioned with lighter cloth and shallower pleating. Below that a simple wrap or a tartan dress is easier for a child to wear all day.
