Fashion sizing is not perfectly consistent between retailers or even between different cuts from the same brand. A familiar size label is a starting point, but measurements and fabric behaviour provide better information.
Take three useful measurements
Measure the fullest part of the bust, the natural waist and the fullest part of the hips. Keep the tape level and comfortably close to the body. Write the measurements down instead of relying on memory.
Read the product details
A fitted woven dress has less tolerance than a stretch jersey style. Look for fabric composition, stretch, garment length and the model measurements. Reviews can highlight whether a style commonly feels small or generous, but individual fit still varies.
Plan for length and alterations
Compare the listed garment length with a dress you own. Petite, regular and tall ranges may change more than the hem. For an occasion purchase, allow enough delivery time to exchange the item or make a simple alteration.
Quick checklist
- Use the retailer-specific chart.
- Check whether measurements describe the body or garment.
- Read fabric and stretch information.
- Keep tags attached until fit is confirmed.
Before you buy
When between sizes, base the choice on the least flexible part of the garment and the intended silhouette. Always check the returns policy before ordering multiple sizes.
Editorial note: Prices, availability and retailer terms can change. Check the retailer website for the latest information before purchasing.
