Quick answer: Look at the tunic and trousers together, then size each piece. A front photograph of the tunic alone cannot tell you whether the full outfit fits.

An áo dài look is easiest to assess when you can see the long tunic and trousers from the front, side, and back. Those views show the tunic’s length, side openings, trouser shape, and how opaque the fabrics appear.

Measure the pieces separately

Compare bust, waist, hips, shoulders, sleeves, and length for the tunic; check waist, hips, and length for the trousers. A well-fitting top does not guarantee a good fit below. Ask whether the trousers shown are included and whether the two pieces can be selected in different sizes.

Shop for the occasion

For a wedding, ask the couple or organizer about color and formality. Shoes, jewelry, and hair accessories in a model photograph may be styling props. A made-to-measure order requires agreement on measurements, fittings, alterations, and delivery date; a ready-made one requires a clear size chart and return terms.

On arrival, dress with your planned base layers and shoes. Check the side view while standing, sit to test the waist and openings, and walk to see how the hem and trouser legs move. Take front, side, and back photos so you can explain any fit issue while there is still time to address it.
