How to Choose Lingerie That Fits Perfectly

Choosing lingerie that fits perfectly is one of the most satisfying purchases you can make, and yet so many of us settle for pieces that are a little too tight, a little too loose or simply not quite right. The secret is that a perfect fit has very little to do with the number on the label. It is about how the fabric sits against your body, how the straps behave and whether you feel confident the moment you put it on. This lingerie size guide is here to help you find that feeling every single time.

When lingerie fits properly, it does something wonderful. It moves with you, holds you comfortably and makes you feel like the best version of yourself. When it does not, even a beautiful piece can feel wrong within minutes. The good news is that getting the fit right is a simple skill anyone can learn, and once you know what to look for, you will never buy a piece that ends up at the back of the drawer again.

Start With Your Measurements

Everything begins with accurate measurements. Measure yourself in a well-lit room with a soft measuring tape, wearing a non-padded bra or nothing at all. Run the tape around the fullest part of your chest, keeping it level and snug but never tight, and note that number down. Then measure the ribcage directly under your bust, making sure the tape sits firmly and straight. These two numbers are the foundation of almost every lingerie purchase you will ever make.

Your waist and hips matter just as much for bodysuits, teddies and sets. Measure your waist at its narrowest point and your hips at the widest part, and always measure twice to be sure. Our bodies naturally shift over time, so it is worth re-measuring every few months even if your weight has not changed. Sizes from different brands do not always match either, so always check the individual size chart before you buy rather than relying on the label alone.

If you are between sizes, think about how the piece will be worn. For delicate pieces designed to be enjoyed in the moment, such as the Leg Avenue Open Cup Crotchless Teddy, going up a size usually gives a more comfortable, flattering drape. For more structured styles that rely on support, follow the band measurement closely, since that is where the real fit comes from.

Understand How Each Style Should Fit

Different styles have different fit rules, and knowing them transforms how you shop. Bras should sit level across the back, with the band firm but comfortable and the cups holding you fully without gaping or digging in. Straps should stay put without slipping, and the centre of the bra should rest flat against your breastbone. If any of those things are off, the fit is wrong no matter what the label claims.

Teddies and bodysuits are all about balance. The fabric should skim your body rather than cling painfully, and the gusset should sit comfortably without riding. Adjustable straps are your best friend here, since they let you fine-tune the length through the torso. A style like the Leg Avenue Cut Out Bodysuit with Thong Back is a lovely example of a piece that is designed to flatter a range of bodies while staying easy to wear.

For bottoms, whether a classic brief or a thong, the edges should lie flat against the skin without pinching or leaving harsh marks. High-cut styles create a longer leg line, while full-coverage briefs offer comfort and support. However you like to wear it, the golden rule is the same: if you adjust it more than once in the first few minutes, it is not the right fit.

Sets that pair a bra with matching bottoms, such as the Leg Avenue Lace Bra Top and Panty with Garters, deserve a little extra attention, because each part should fit well on its own before you consider the combination. Once the individual pieces work, the set will always look pulled together and polished.

Small Fixes That Change Everything

Sometimes a piece that is almost right can be made perfect with a tiny adjustment. Learn to use the different hook positions on your bra, since a band that is comfortable on the loosest hook in the shop will need the tighter hooks as the fabric stretches. Most bodysuits and teddies have adjustable straps, so take a moment to tweak them for your exact torso length rather than leaving them at the default setting.

Choosing the right legwear completes the picture. A pair of Leg Avenue Stay Up Sheer Thigh Highs that fits well stays in place all evening, and the sheer fabric flatters every leg shape. Take your time to find hosiery with a comfortable top band, because that is where the fit lives or dies. If the thought of putting together a full outfit feels daunting, our bodysuits and teddies collection has plenty of complete looks that take the guesswork out of matching.

Finally, trust your own judgment over the label. Size charts are a starting point, not a verdict, and two different brands can size the same body differently. When a piece makes you feel good and moves with you comfortably, that is the definition of a perfect fit. For a full range of styles to try, from bras and panties to stockings and hosiery, browse the collection and enjoy the process of finding what suits you best.

Frequently Asked Questions

What size lingerie should I buy if I am between sizes?

Go up a size for soft, delicate pieces that should drape beautifully, and follow the band measurement closely for structured, supportive styles. Checking the individual size chart for each brand is always the safest route.

How do I know if a bra fits correctly?

The band should sit level and firm across your back, the cups should hold you without gaping or digging in, and the centre panel should rest flat against your breastbone. Straps should stay put without digging into your shoulders.

Do bodysuits fit differently to bras?

Yes. Bodysuits and teddies are all about length through the torso and comfort at the gusset. Adjustable straps are essential for getting that length right, and the fabric should skim your body rather than cling too tightly.
