Shopping for your little girl online is exciting as well as convenient—there’s no shortage of adorable dresses to click “add to cart” on from the comfort of your residence. But if there’s one thing parents worry about most, it’s this: getting the size right.
Just like adults, little girls have different body types and sizing needs. Two children of the same age can wear completely different sizes, which makes choosing the right fit tricky. Add to that the fact that kids often know what they like (comfort, twirl factor, colors!)—and the stakes get higher when shopping online.
That’s why selecting the right size is so important. The dress should not only fit perfectly today but also allow a little room for those inevitable growth spurts. This is especially true with 100% cotton dresses, which are loved for their comfort and breathability—but don’t have the stretch of synthetic fabrics.
If you’re wondering, “How do I choose the right size when buying cotton dresses for girls online in the US?” this guide will walk you through it.
At Gobblefunk, we specialize in pure cotton dresses for girls aged 2 to 7. Here’s everything you need to know before hitting that checkout button.
1. Understand US Standard Kids’ Sizing
In the US, children’s clothes are often sized by age: 2T, 3T, 4T, and so on, up to 7 years. But every child grows differently—so relying on the number alone can be misleading.
Quick tip:
- T (as in 2T, 3T) generally means toddler sizing, cut with extra room for diapers.
- Beyond size 4, clothes usually lose the “T” and are cut slimmer.
That’s why measurements matter more than the tag.
2. Always Check the Brand’s Size Chart
Not all brands size their clothes the same way. A size 4 at Old Navy can feel looser than a size 4 at Carter’s, for example.
That’s why you should always:
- Measure your child’s chest, waist, and height.
- Compare these numbers to the brand’s size chart.
At Gobblefunk, we provide a detailed size guide for ages 2–7, so you know exactly what to expect before ordering.
3. Factor in Cotton’s Natural Fit
Here’s the beauty of cotton:
- It’s breathable, soft, and perfect for sensitive skin.
- But unlike jersey or polyester blends, cotton doesn’t stretch.
That means getting the right size upfront is crucial. If your child is between two sizes, we recommend sizing up. That way, she has room to move, play, and grow—without the dress feeling restrictive.
4. Think About Growth Spurts
Parents know this better than anyone: kids grow fast. A dress that fits perfectly today might be short in three months.
- For everyday wear in summer, true-to-size works well.
- For year-round use, especially if you want layering options (like tights or tees underneath), consider going one size up.
Gobblefunk’s cotton dresses are designed to be comfortable whether worn alone in warm weather or layered for cooler months.
5. Don’t Skip Reviews & Return Policies
One of the perks of shopping online in the US is easy returns. Many big retailers like Target, Amazon, and Walmart offer flexible policies—and at Gobblefunk, we’re committed to the same.
As our new brand grows, customer reviews will be your best friend. Reviews from other parents give real-world feedback on whether a dress runs big, small, or true to size. Until then, our detailed sizing chart has you covered.
6. Quick Sizing Checklist Before You Buy
Here’s a simple routine to follow when shopping online for cotton dresses:
Take fresh measurements of your child.
Compare with the US size chart (never guess by age alone).
Remember cotton = no stretch, so size up if in doubt.
Check return and exchange policies.
Do this, and you’ll almost never go wrong.
