38 can mean different US sizes depending on whether you mean EU clothing or EU shoes , and whether it’s for men or women.

Quick Scoop

1. If you mean EU clothing size 38 (very common)

For most women’s clothing charts, EU 38 ≈ US 6 (sometimes US 6–8 depending on brand and fit).

  • Dresses/tops: usually around US 6.
  • Pants/skirts: often US 6, but some brands call it US 6–8.

So if your tag just says “38” in a European women’s brand, in the US you’d normally try a US size 6.

2. If you mean shoe size 38

For shoes, EU 38 converts differently:

  • Women’s shoes: EU 38 ≈ US 7.5.
  • Men’s shoes: EU 38 ≈ US 6–6.5 in many charts.

So a “38” on European sneakers or heels is usually a US 7.5 women’s or 6–6.5 men’s.

3. If you mean “US size 38” (already US)

If the label already says “US 38”, that’s usually:

  • Men’s pants/jeans/waist: US 38 is just 38 in the US system (about a 38‑inch waist), and converts to around EU 54 in some charts.

In that case, you’re already seeing the US size.

Tiny forum-style TL;DR

“38is what size in us?”

  • EU clothing 38 → usually US 6 (women).
  • EU shoe 38 → about US 7.5 women / 6–6.5 men.
  • “US 38” on pants → it’s already a US 38 (≈ EU 54).

Because brands vary, the safest move is always to check that brand’s own size chart and your body or foot measurements. Information gathered from public forums or data available on the internet and portrayed here.
