Quick Answer

To measure for a babydoll or teddy, take your bust, waist, and hip measurements with a soft tape measure. Compare those numbers to the brand’s size chart — stretchy mesh styles are more forgiving, while structured lace or satin pieces need a closer match.

How to Take Your Measurements for a Babydoll

Use a soft, flexible tape measure and wear little to no clothing. Stand straight with your feet together. For the bust, measure around the fullest part of your chest, keeping the tape level across your back. For the waist, find the narrowest part — usually just above your belly button — and measure snugly without compressing the skin. For the hips, measure around the widest point, typically 7–9 inches below your waist. Write down each number in inches or centimeters, depending on the size chart you’ll use.

If you’re between sizes, consider the fabric. Stretchy mesh or knit babydolls (like the Lace by LJ Rainbow Halter Neck Dress) can accommodate a range, while non-stretch satin or lace pieces may need the larger size. Always check the specific brand’s size chart — a “one size” in one line may fit differently than in another.

What’s the Difference Between a Babydoll and a Teddy?

A babydoll is a short, loose-fitting nightie that typically ends at the upper thigh. It often has an empire waist, built-in shelf bra, and sheer or flowing fabric. A teddy is a one-piece bodysuit that snaps at the crotch — it’s more fitted and shows off your shape. Both are measured the same way (bust, waist, hips), but teddies require a closer fit through the torso because they’re meant to stay in place without riding up.

How Do Plus Size Babydolls Fit?

Plus size babydolls and teddies are cut with extra room through the bust, waist, and hips, but the same measuring rules apply. The Lace by LJ Plus Size Long Sleeved Cut Out Back Bodysuit, for example, uses a stretch fabric base with sheer mesh panels — the stretch helps it conform to your curves, while the lace-up front lets you adjust the fit slightly. If you’re at the top end of a size range, look for styles with adjustable ties, stretch lace, or open backs that offer more flexibility.

Babydoll Sizing FAQs

Should I size up or down in a babydoll?

Size up if you’re between sizes and the fabric has little to no stretch (e.g., satin, non-stretch lace). Size down only if the style is intentionally oversized and you want a closer fit. For stretchy mesh babydolls, your regular size usually works. When in doubt, size up — a slightly loose babydoll still looks intentional, but a tight one can gap or ride up.

How do I know if a one-size babydoll will fit me?

Check the brand’s size chart for the specific garment. “One size” often covers a range like US 4–10 or 8–14, but that varies. Look at the fabric content — high spandex or elastane content means more give. If the chart doesn’t list measurements, contact customer service or choose a sized style. Don’t assume “one size” fits all. Always check the actual measurement range.

Can I wear a babydoll if I have a large bust?

Yes, but look for styles with built-in shelf bras, adjustable straps, or stretch lace at the bust. Babydolls with an empire waist skim over the midsection and don’t rely on a perfect bust fit, so they’re often more comfortable for fuller busts than a fitted teddy. Empire-waist babydolls are bust-friendly. For teddies, prioritize stretch fabric and adjustable details.
