Ralph Lauren Sizing: Runs Large in Some Items, Slim in Others

Ralph Lauren has multiple sub-brands — and sizing varies slightly between them. That said, the brand generally favours a more relaxed, American-style fit, especially in Polo shirts, knitwear, and classic trousers. However, certain ranges like Ralph Lauren Collection (women’s) or Purple Label (men’s) are tailored and run slim.

Women’s Fit Overview

  • Lauren Ralph Lauren: Cut for comfort and runs slightly large, especially in dresses and knitwear.

  • Polo Ralph Lauren: More fitted and contemporary — true to size, but go up if between sizes.

  • Ralph Lauren Collection: Tailored and structured — runs small, especially in dresses and jackets.

  • Shirts & Blouses: True to size, but slim through shoulders and bust — size up for ease.

Men’s Fit Overview

  • Polo Shirts: Come in Classic, Custom Slim, and Slim fits. Classic runs large, Slim is closer to UK fit.

  • Oxford Shirts & Dress Shirts: True to size, but tailored fits run small in the chest and shoulders.

  • Knitwear & Jumpers: Relaxed fit — go true to size or size down for a neater silhouette.

  • Trousers: Chinos and cords tend to be true to size, though older styles may have a longer rise.

Fabric & Fit: What Affects Sizing in Ralph Lauren

Ralph Lauren’s extensive product line means fabrics vary widely. These can change the way a garment fits:

  • Oxford cotton – classic button-down shirts; crisp and tailored

  • Pima cotton – used in polo shirts and knitwear; breathable and soft

  • Linen blends – looser fit, perfect for summer collections

  • Structured wool or silk – more tailored, runs small in the bust/shoulder for women

The key takeaway: casualwear fits big, tailoring fits slim, and different sub-labels behave differently.

Sizing Tips for Ralph Lauren Shoppers

  • Always check the sub-label: Polo, Lauren, Purple Label and Collection all size differently

  • Tailored = smaller: Jackets, formal dresses and shirts run slim

  • Polo shirts vary by fit:

    • Classic Fit = relaxed, boxy — ideal for layering

    • Custom Slim Fit = tailored through the waist

    • Slim Fit = narrow across shoulders, chest, and sleeves — size up if you prefer room

  • European shoppers take note: US Ralph Lauren sizes can feel larger than UK equivalents

  • Lauren Ralph Lauren (women’s line) is designed to flatter curvier bodies — slightly more generous through the waist and bust

  • Purple Label and Ralph Lauren Collection pieces are designer-cut and slim — treat them like luxury tailoring, not high street sizing
