UK sizing answer
Does Under Armour Run Small?
Forre is still collecting enough reviews to give a confident Under Armour sizing verdict.
Community fit data is growing. Based on brand sizing information and product specifications.
Fit notes
Runs true to size. HeatGear fabric is excellent for sweaty high-intensity activity. The Infinity High bra offers genuine encapsulation for D+ cup — rare in activewear. Rush Seamless provides energy-return compression for heavier training.
Watch out for
Less fashion-forward aesthetic than UK-native brands. Rush range runs quite firm — size up if you prefer moderate compression over maximum.
