Zara
Runs small. Consider sizing up one size from your usual US size.
H&M
Runs about half a size small. May need to size up for a comfortable fit.
ASOS
Generally true to size. Uses UK sizing predominantly, so check their size guide.
Target (US)
Tends to run large due to vanity sizing. You may need to size down.
