Is Lululemon size 6 a small or medium?
A Lululemon 6 is a Small. On Lululemon's own chart the letters run 0 = XXXS, 2 = XXS, 4 = XS, 6 = S, 8 = M, 10 = L, 12 and 14 = XL — so a 6 is the largest size still called Small, and Medium does not start until 8. The brand sizes by US number rather than letters, so a 6 fits like a US 6 (roughly UK 10, EU 38).

Lululemon Sizing & Fit Guide
Lululemon sizes women's apparel by US number (0–20) rather than letters, and is generally true to size. Their own letter mapping is tighter than most people expect — a 6 is Small, an 8 is Medium, and a 10 is already a Large. Compression styles (Align, Wunder Train) fit snug by design, so size up only if you want a relaxed feel. Lululemon publishes body measurements but no UK or EU equivalents — the UK/EU columns below use standard international conversions for orientation.
How Lululemon Sizing Works (0–20)
Unlike most athleticwear brands, Lululemon sizes women's apparel by US dress number — 0, 2, 4, 6, 8, 10, 12, 14, and up to 20 on extended lines — instead of XS/S/M/L. Lululemon does publish the letter each number corresponds to, and it is worth reading carefully because it is tighter than most people assume: 0 is XXXS, 2 is XXS, 4 is XS, 6 is S, 8 is M, 10 is L, 12 and 14 are both XL, 16 and 18 are 1X, and 20 is 2X. Note that Small covers only size 6, and Medium only size 8 — a 10 is already a Large. Lululemon's size guide also publishes body measurements (bust, waist, hip) so you can match your own, but it does not print UK or EU clothing-size equivalents — those only appear on its shoe charts. The UK and EU figures in the table above are standard international conversions to help you orient, not numbers from Lululemon's chart.
Does Lululemon Run True to Size?
Lululemon is generally true to size, but fit depends on the line. Compression styles like Align and Wunder Train are engineered to feel snug and supportive, so they can read small if you expect a relaxed fit — go up one only if you want extra room. Looser pieces (Scuba hoodies, joggers, the Softstreme range) are roomier and many shoppers keep their usual size or even size down. Because cut varies so much by style, Lululemon advises checking the specific garment measurements on each product page.
