3|Welcome to the AngelofYou comprehensive lingerie buying guide. Whether you're looking for your first bra or adding to your collection, this guide covers everything: sizing, fabrics, styles, and care. / 欢迎来到AngelofYou内衣选购完全指南，从尺码到面料到款式，一站式搞定。
4| 5| 6|Part 1: How to Choose the Right Bra Size | 如何选对内衣尺码
8| 9|Step 1: Measure Underbust | 测量下胸围
10|Stand straight, wrap measuring tape snugly around your ribcage directly under your bust. Keep level. Record in inches. If odd, round up to nearest even — this is your band size. / 站立，软尺紧贴肋骨绕下胸围一圈，保持水平，记录英寸数，奇数则向上取偶数为底围。
11| 12|Step 2: Measure Overbust | 测量上胸围
13|Wrap tape around the fullest part of your bust, parallel to floor, snug but not tight. Record in inches. / 软尺绕过胸部最丰满处，保持水平，不压紧，记录英寸。
14| 15|Step 3: Calculate Cup | 计算罩杯
16|Subtract band from bust: 1"=A, 2"=B, 3"=C, 4"=D, 5"=DD/E. / 上胸围减下胸围：1寸=A，2寸=B，3寸=C，4寸=D，5寸=DD/E。
17| 18|| Difference / 差值 | Cup / 罩杯 |
|---|---|
| 0-1" | AA |
| 1-2" | A |
| 2-3" | B |
| 3-4" | C |
| 4-5" | D |
| 5-6" | DD/E |
Sister Sizing | 姐妹尺码
29|If a size feels off, try sister sizes: same cup volume, different band. E.g., 34C ↔ 32D ↔ 36B. Go up a band, down a cup; down a band, up a cup. / 如果穿着不合适，尝试姐妹尺码：罩杯容量相同，底围不同。底围大一码则罩杯小一码，反之亦然。
