How we sized thissized by bust
  • Sold as letter sizes (XXS–XL). If your product’s size options look different, use the tab that matches them.
  • One PacSun chart covers its women’s tops, graphic tees, sweaters, sweatshirts and dresses, sized by your bust with the waist as a check. PacSun’s size buttons print the letters as XXSML, XS, SML, MED, LRG and XLG: the XXS to XL here. Its guide pairs them with US sizes: XXS is a 0, XS a 2, S a 4, M a 6, L an 8 and XL a 10.
  • Most PacSun tops also come in XXL (XXLRG), which PacSun’s tops chart doesn’t measure: it stops at XL, a 42½″ bust. So XXL has no row here, and past 42½″ we can’t size you on this tab.
  • Swim tops open the same guide on its Swim tab: the same bust as this chart for XXS to L, with bra sizes beside each letter (an M covers 32DD, 34C, 34D and 36B), an XL of 42½–44″ and an XXL of 45–46½″.
