Sunday Best (Aritzia) Ruched Cap-Sleeve Shirt Dress – Navy | Size XS

A feminine take on the classic shirtdress, this Sunday Best by Aritzia mini dress combines crisp cotton shirting with a softly shaped, figure-skimming silhouette. The deep navy colour keeps it polished and versatile, making it an especially easy piece to transition from late summer into early fall.

Designed with a pointed shirt collar and full button front, it features softly gathered cap sleeves and ruching through the bust for subtle shape. A defined waist creates a flattering silhouette, while the smocked elastic panel at the back waist adds stretch and comfortably contours the fit. The cotton-blend fabric has a touch of elastane for added ease of movement.

Late Summer → Pre-Fall Styling

For late summer, keep it simple with a leather sandal, ballet flat or loafer and a woven or structured shoulder bag. The navy also looks beautiful with warm tan or cognac leather accessories and gold jewellery.

Transitioning to fall, as temperatures start to shift, lean into the dress’s slightly preppy, ’90s-inspired shirtdress feel with loafers and socks, a slim leather belt and structured bag. Very cute with a cropped/natural waist knit sweater over it making it look like a collar pop, or add a cardigan over the shoulders for early fall, then transition it further with a trench, oversized blazer or cropped leather jacket and tall boots.

For a more fashion-forward look, I’d also style it with a chunky loafer, sheer sock and oversized menswear blazer — the sharper proportions would balance the fitted waist and feminine cap sleeve really nicely.

An easy transitional mini that feels polished without being overly dressy — equally good for everyday wear, work, dinner or an early-fall layered look.
