Fast Fashion Brands

Zara

H&M, being a Swedish brand, also uses European sizing. Their sizing varies significantly between different collections and can be quite inconsistent. H&M Conscious and H&M Trend lines may fit differently than their basic line.

Forever 21

Forever 21 sizing is notoriously inconsistent and generally runs small. The brand targets a younger demographic and their sizing reflects junior sizing standards. Quality control issues mean sizing can vary even within the same style.

Tips for Cross-Brand Shopping

Always Check Size Charts

Never rely solely on size labels when shopping across different brands. Always consult the brand's specific size chart and compare your measurements.

Read Customer Reviews

Customer reviews often contain valuable sizing information. Look for reviews from people with similar body types and measurements.

Consider the Garment Type

Even within the same brand, different types of clothing may fit differently. A brand's t-shirts might run large while their jeans run small.

Factor in Fabric and Stretch

Stretchy fabrics will fit differently than non-stretch fabrics. Consider how much give the fabric has when determining your size.

Know Your Return Policy

When trying a new brand, make sure you understand their return policy. Many brands offer free returns, allowing you to order multiple sizes.
