There's something about a matching bra and panty that makes you feel put together, even when nobody else can see it. But buying a lingerie set online can feel like a gamble. The bra fits perfectly and the panty is too tight. Or the panty is great and the bra gaps.
That happens because your bra size and your panty size are measured from two completely different parts of your body, so they don't always line up the way a set is packaged. Here's how to make sure both pieces fit.
H2: What Is a Lingerie Set?
A lingerie set is a bra and panty designed to be worn together, made in the same fabric, colour and detailing. Some sets are everyday essentials in soft cotton or seamless fabric. Others are made for occasions, with lace, prints or a bolder cut.
SOIE's lingerie sets for women include both: easy daily pairs and prettier sets for special days.
H2: Why Bra and Panty Sizes Don't Always Match
Your bra size depends on your underbust and bust measurements. Your panty size depends on your waist and hips. Two women can both wear a 34C and have very different hip measurements.
That's why most sets are sold as a paired size, for example Bra 34C with Panty M. The pairing follows the most common body proportions, and it works for many women, but not all.
H3: How SOIE pairs set sizes
On most SOIE lingerie sets, the band size decides the panty size:
|

Panty size in the set |
|
30 and 32 |
S |
|
34 |
M |
|
36 |
L |
|
38 |
XL |
|
40 |
XXL |
|
42 and 44 |
XXL or 3XL (varies by set) |
Check the size options on each product page, as a few sets are sold in S to 5XL sizing instead.
H2: How to Find Your Size for a Lingerie Set
Grab a soft measuring tape and measure in front of a mirror, wearing a non-padded bra or none at all.
H3: Measuring for the bra
-
Underbust: Measure snugly around your ribcage, just under your bust. This gives your band size.
-
Bust: Measure loosely around the fullest part of your bust, keeping the tape level.
-
Cup: The difference between the two numbers gives your cup size. Every inch of difference is roughly one cup size up.
Our guide on finding the right bra size when buying online walks you through this in more detail.
H3: Measuring for the panty
-
Waist: Measure around the narrowest part of your waist.
-
Hips: Measure around the fullest part of your hips and bottom.
Compare these with the panty size chart. If your waist and hips fall into different sizes, go by your hips. For a full chart, see our panty size chart for India.
H2: What If Your Sizes Don't Match the Set?
Say you're a 34C bra, which comes with an M panty, but your hips measure as an L. You have a few options:
-
Pick your bra size first if support matters more to you. A slightly snug panty is easier to live with than an ill-fitting bra.
-
Choose a set with a stretchier panty. Seamless, lace and high-rise briefs usually have more give than cotton bikinis.
-
Build your own set. Buy the bra and a matching panty separately in the sizes you need, where the same style is sold on its own.
-
Check the exchange policy before you order. SOIE's returns and exchange policy explains how exchanges work.
H2: What to Check Before Buying a Lingerie Set Online
Read the product page carefully. Look for:
-
Paired size options (Bra 34C / Panty M) and whether yours is available
-
Padding and wiring, to match your everyday preference
-
Coverage of both pieces, since a full coverage bra with a cheeky panty may not be your style
-
Panty rise, whether low, mid or high rise
-
Fabric, since cotton is breathable, lace is delicate and seamless blends are smooth under clothes
H2: Which Lingerie Set Suits Which Occasion?
H3: For everyday wear
Look for soft, smooth sets you can wear for 10 hours without thinking about them. The Full Coverage Padded Seamless Bra & High-Rise Brief Set disappears under fitted clothes.
H3: For a fuller bust
A minimiser set gives support and a streamlined look. Try the Full Coverage Minimiser Bra with High Waist Brief Set.
H3: For special occasions
Lace sets feel pretty without sacrificing comfort. The Full Coverage Padded Bra and Mid Rise Brief With Lace Detailing is a good middle ground. If you're shopping for a wedding, our list of lingerie set must-haves for brides is a helpful place to start.
How to Care for a Lingerie Set So Both Pieces Last
Wash the bra and panty together, by hand, in cool water. That way they fade at the same rate and stay matched for longer. Dry them flat in the shade and never tumble dry. Our lingerie care guide has the full routine.
Lingerie Set FAQs
Can I buy a lingerie set in different sizes?
Most sets come in fixed pairs. If your sizes don't match the pairing, buy the bra and panty separately where the style is sold individually.
Are lingerie sets comfortable for daily wear?
Yes. Choose sets in cotton, modal or seamless fabrics with non-wired or lightly padded bras for all-day comfort.
What fabric is best for a lingerie set?
Cotton blends for breathability, seamless fabric for a smooth look under clothes, and lace for occasions.
Should I size up or down if I'm between sizes?
For the panty, size up for comfort. For the bra, choose the band that feels snug on the loosest hook.
Match the Look, Fit Each Piece
A lingerie set should look coordinated, but each piece still has to fit your body on its own terms. Measure both your bust and your hips, check the paired sizes, and you'll end up with a set you actually reach for, not one that sits in the drawer.
