How to Choose the Right Bra Size: A Simple Guide for Women 30+

Finding the perfect bra can feel overwhelming, especially when your body is changing with age, motherhood, or weight fluctuations. At SweetCurves, we design bras that prioritize comfort, support, and style—no underwires, no digging, just confidence. But the first step to comfort is choosing the right size. Here's your go-to guide to finding your best fit.
1. Start with Measurements
To get your most accurate bra size, you'll need two key measurements:
-
Bust Size: Measure around the fullest part of your bust (usually across the nipples), making sure the tape is level and not too tight.
-
Underbust Size: Measure just under your breasts, snug but not tight.
Use our size guide below to find your band size:
Band Size | Under Bust (in) |
---|---|
30 | 26.5 - 28.5 |
32 | 28.5 - 30.5 |
34 | 30.5 - 32.5 |
36 | 32.5 - 34.5 |
38 | 34.5 - 36.5 |
40 | 36.5 - 38.5 |
42 | 38.5 - 40.5 |
44 | 40.5 - 42.5 |
2. Determine Your Cup Size
Subtract your underbust measurement from your bust measurement. The difference tells you your cup size:
-
1 inch = A cup
-
2 inches = B cup
-
3 inches = C cup
-
4 inches = D cup
-
5 inches = DD/E cup
-
6 inches = DDD/F cup
-
7 inches = G cup
-
8 inches = H cup
Example: If your bust is 40" and your underbust is 34", the difference is 6 inches = DDD/F cup. Your band size based on 34" underbust is 34, so your bra size is 34DDD/F.
3. Use Our Size Chart
Once you know your band and cup size, find your fit in our SweetCurves size chart:
Example:
-
36C = XL
-
38B = XL
-
40DD/E = 3XL
-
42DDD/F = 4XL

4. When in Doubt, Size Up for Comfort
Our bras are made with stretchy, supportive fabric designed to adapt to your body. If you're between sizes, we recommend sizing up for a more comfortable, relaxed fit.

Why Fit Matters More As You Age
As we enter our 30s, 40s, and beyond, our bodies shift—from pregnancy, weight gain or loss, or simply the natural aging process. That means the bra size you wore in your 20s may not be right anymore. A proper fit:
-
Lifts and supports
-
Improves posture
-
Reduces shoulder and back pain
-
Enhances confidence in every outfit
At SweetCurves, we celebrate every curve, every stage of life.
