The right size starts with the brand’s size chart and your body measurements. Begin by measuring bust, waist, and hips, then compare them to the chart for L’Agence and Akiya tank dresses. Consider the intended silhouette—whether you want a snug or relaxed fit—and factor in fabric stretch and dress length. If you’re between sizes, choose the larger size for comfort or the smaller one for a closer silhouette.

Fabric stretch and cut are the key complexities. Stretchy fabrics provide more ease, so you may size down for a fitted look or stay with your usual size for a forgiving fit. Woven fabrics with little stretch often require sticking closer to your bust, waist, and hip measurements. Always check how the silhouette is intended to sit—whether it skims the body or drapes with ease—and adjust accordingly.

Yes, beginners typically prefer a relaxed fit, choosing a size that comfortably accommodates the bust and hips. Seasoned shoppers may aim for a sharper silhouette by matching measurements more closely. For different uses—office wear, casual weekends, or layering—adjust your size toward comfort, sleekness, or flexibility as needed.

Follow the care label instructions to protect fit over time. Use gentle washing, avoid high heat, and air-dry when possible to prevent shrinkage or distortion. Refrain from wringing and store the dress on a hanger or flat to keep its shape consistent.

Brand sizing can vary, so always compare your measurements against each brand’s size guide. Have bust, waist, and hip measurements ready and calculate where you fit on both charts. If in doubt, choose the size that feels most comfortable and take advantage of flexible returns.

Check the store’s return or exchange policy and start a size swap if available. Gather your measurements and the size chart reference to choose a new size, and ensure the garment is unworn and in original condition for a smooth exchange.
