Direct answer
Choose by band, coverage and daily outfit.
A 40D bra for everyday wear should not be judged only by the cup letter. The band needs to stay level, the wire should feel supportive without sharp pressure, and the cup finish should match the clothing you actually wear.
| Need | Look for |
|---|---|
| T-shirt days | Fabric cups and a smoother side finish. |
| More coverage | 3/4 cup styles for a more contained front profile. |
| Lower neckline | 1/2 cup styles when the outfit needs a lower front profile. |
