About this chart

A British guide: the reference size is the UK size. Marks & Spencer publishes in inches and centimetres; only centimetres are reproduced. Kids' trouser lengths and men's suit lengths, which are garment measurements, are not reproduced, nor are premature baby sizes.

Women

One chart for dresses, tops, bottoms, skirts, swimwear, nightwear and the Petite range (up to 18). Trouser inside leg: 69 cm (Extra short, Petite), 73 cm (Short), 79 cm (Regular), 85 cm (Long). Equivalents come from the dual-size chart (UK 8-10 = EU 36-38), which does not cover UK 6.

Bras — band size in other countries

Marks & Spencer publishes no measurements for its bras, only a conversion table: UK band 34 is 90 in France and 75 in Europe, and cup letters change after D (UK DD = European E, UK G = I). The US row, one cup off, is not reproduced.
