This is an olive green, three-quarter sleeve dress, likely a shift or A-line style, with a partially open back that features a detail at the top. The dress has a slight sheen, suggesting it is made from a material like satin or a woven fabric with a similar finish. The European size is 40, which is equivalent to a US size 10. A size 40 dress from H&M corresponds to a bust measurement of approximately 36¼ - 37¾ inches and a waist measurement of 30 - 31½2 inches. How to Style It • Jewelry: The olive green color pairs well with both warm and cool-toned metals. Gold jewelry can provide a warm, sophisticated contrast, while silver offers a modern and sleek look. Rose gold adds a romantic touch. • Layering: For a casual daytime look, the dress can be layered with a denim jacket. A leather jacket can create a bolder statement. • Footwear: The dress can be paired with sandals for a breezy daytime outfit or elevated with heels for an evening event. • Makeup: To complement the olive green color, makeup can include gold, bronze, or earthy tones for eyeshadow, with a soft pink or nude lip color.
