From retro party outfits to Halloween favorites, the right fit helps you look great and feel comfortable. Use our sizing tips and reference charts to shop with confidence.
Measure your body using a flexible tape measure. For the most accurate results, have someone assist you.
Costume sizing varies by manufacturer. Always compare your measurements with the size chart on the product page when one is available.
Consider the costume's cut, fabric, layering, and comfort. When between sizes, a larger size may offer more flexibility.
Important: The charts below provide general costume size references, not guaranteed measurements for every product. Manufacturer size charts and individual product information should always take priority.
Not every costume is available in every size.
Women's costume sizes commonly use familiar clothing size labels, but fitted, vintage-inspired, and specialty costumes may fit differently from everyday clothing.
| Costume Size | Approximate US Clothing Size |
|---|---|
| X-Small (XS) | 0–2 |
| Small (S) | 4–6 |
| Medium (M) | 8–10 |
| Large (L) | 12–14 |
| X-Large (XL) | 16–18 |
| Plus | Up to 20W in some styles; check product details |
| Standard / One Size | Often labeled up to US 12; varies by product |
| Fitted / "Sexy" Styles | Some are labeled up to US 10; check product details |
Women's Fit Tip: Pay particular attention to bust, waist, and hip measurements. A costume described as fitted may offer less room than a relaxed or stretchy style.
Men's costume sizing often uses chest or jacket-size references. The following is a general guide based on traditional costume size labels.
| Costume Size | Approximate Inch-Based Size Reference |
|---|---|
| Small (S) | 36–40 inches |
| Medium (M) | 40–42 inches |
| Large (L) | 42–44 inches |
| X-Large (XL) | 44–46 inches |
| Standard / One Size | Often labeled up to 44 inches |
Men's Fit Tip: These ranges are approximate references from traditional costume sizing, not a universal body-measurement chart. Check whether the manufacturer specifies chest, jacket, waist, or garment dimensions.
Taller shoppers should also consider inseam, sleeve length, and overall costume length.
Children's costumes may be labeled by age group, clothing size, or height. Because children grow at different rates, measuring is often more useful than choosing by age alone.
| Costume Size | Approximate US Size |
|---|---|
| Toddler | 2–4 |
| Small | 4–6 |
| Medium | 8–10 |
| Large | 12–14 |
| Teen | 14–16; some older costume charts compare this with women's 0–2 |
Parents' Tip: Check your child's height and the actual costume measurements. For Halloween, consider whether the outfit needs room for comfortable movement or additional clothing underneath.
You don't need special equipment— just a flexible measuring tape. Measure over lightweight clothing, stand naturally, and avoid pulling the tape too tightly.
Measure around the fullest part of your bust or chest, keeping the tape level around your back.
Measure around your natural waistline, generally above the hips. Keep the tape comfortably snug.
Measure around the fullest part of your hips and seat, with your feet together.
Check overall height and relevant garment lengths, particularly for jumpsuits, robes, dresses, and full-length costumes.
Compare these measurements with the manufacturer's chart on the individual product page. If the product lists garment dimensions rather than body measurements, allow room for comfortable movement.
