Different Brands, Different Dress Sizes

The first thing that many parents notice is the variation in girls' dress sizes from one label to another. For example, a size for a 12-year-old girl might seem tight in one store and loose in another. The result is a brand's perception of sizing and brand fit. One very good reason this can occur is that one brand prefers a slim fit while another brand might prefer a more relaxed fit. So, before you base the decisions only on the age or size of children’s dress, always double-check the size chart of the brand you are looking at. Here are few quick steps to help you:

Check the brand's size chart - Sizing can vary, for example when is 11-12 years for girls, measure you child's measurements against the chart.

Think about ease - At the same time, it is good to allow for a bit of extra room to provide ease of movement so your child can run, dance or play.

Think about the style - A girls frock style may fit differently than a straight cut dress. However, you can be assured that when you purchase One Friday dresses, comfort goes with style.

The Role of Fabric & Style in Dress Fit and Comfort

When it comes to picking the right dress size for a 12-year-old girl, both the fabric and style are just as important as the measurements.

Fabric: Soft, breathable materials like cotton or linen will keep your child comfy all day long, while fabrics like silk or chiffon can add a touch of elegance for special occasions. It's best to steer clear of fabrics that feel stiff or scratchy.

Style: A girls' frock provides plenty of room and freedom to move, making it perfect for active kids, whereas a fitted dress might be more suitable for formal events.

Season: In the summer, opt for lighter fabrics; in the winter, go for warmer options like wool blends.
