Shopping at Chico's requires learning a completely different numerical language than standard retail sizing. If you've ever stared at a rack of jackets or pants marked with sizes like 0, 1, 2, or the elusive 000, you know traditional vanity sizing won't help you here. Chico's uses a proprietary sizing system designed to fit distinct body proportions across misses, petite, and plus categories.
Understanding how this proprietary system maps to standard US department store sizes eliminates the guesswork from online shopping and fitting room trips. This guide breaks down the exact measurement conversions, explains how Chico's labels translate to numeric sizes, and provides practical steps to find your ideal fit on the first try.
The Chico's Sizing Framework: From 000 to 4
Unlike standard retail sizing that uses even numbers like 2, 4, 6, and 8, Chico's relies on a single-digit scale ranging from 000 up to 4. Each number covers a two-size span in traditional American retail.
To make sense of the rack, you have to memorize how these numbers map to standard sizing. Here is how the core scale breaks down:
- Size 000: Equivalent to a traditional US size 0 or 2 (XXS / Petite XS)
- Size 00: Equivalent to a traditional US size 4 (XS)
- Size 0: Equivalent to a traditional US size 6 or 8 (Small)
- Size 1: Equivalent to a traditional US size 10 or 12 (Medium)
- Size 2: Equivalent to a traditional US size 14 or 16 (Large)
- Size 3: Equivalent to a traditional US size 18 or 20 (XL / 1X)
- Size 4: Equivalent to a traditional US size 22 or 24 (XXL / 2X)
Because each Chico's size covers two traditional sizes, garments are engineered with high-recovery stretch fabrics, drape-forward cuts, and adjustable elements to maintain a tailored look across both ends of the range. If you fall right on the boundary between two numbers, your choice depends entirely on your preferred fit. Size down for a body-skimming, structured silhouette, or size up for a relaxed, fluid drape.
Taking Accurate Body Measurements
Relying on guesswork or the size of a top you bought five years ago leads to poor fits. To use the official Chico's Size Guide with confidence, grab a flexible fabric measuring tape and record three baseline numbers while wearing fitted clothing or undergarments.
- Bust: Wrap the tape horizontally around the fullest part of your bust, ensuring the tape stays parallel to the floor across your back. Do not pull the tape tight; keep it comfortably snug.
- Natural Waist: Bend to one side to find the natural crease of your torso. Measure around this narrowest point. If you carry weight in your midsection, measure about an inch above your belly button where high-rise pants typically sit.
- Hips: Stand with your heels together and measure around the fullest part of your hips and rear, usually about 7 to 9 inches below your natural waistline.
Write down these measurements in inches and centimeters. When comparing them to the brand's sizing tables, always prioritize your bust measurement for tops, jackets, and dresses, and your hip measurement for trousers, jeans, and skirts.
Navigating Misses, Petite, and Plus Proportions
One common pitfall when reading a Chico's size chart is ignoring height and torso proportions. The brand designs collections across specific silhouettes that account for vertical distribution, not just horizontal girth.
If you are 5 feet 4 inches or under, standard tops and pants may overwhelm your frame, even if the numeric size matches your chest measurement. Chico's offers dedicated petite versions of many popular styles, indicated by a "P" designation or found in their dedicated petite section. Petite sizes shorten sleeve lengths, torso drops, and inseams by roughly one to two inches without tightening the overall width.
Conversely, if you need extended sizing, sizes 3 and 4 are cut specifically with fuller figures in mind, ensuring armholes, necklines, and rise depths scale comfortably rather than simply stretching the fabric. For official product care and specific garment stretch ratios, you can reference details directly on the Chico's Official Site.
Common Sizing Mistakes and How to Avoid Them
Even seasoned shoppers run into trouble when transitioning brands. Keep these frequent missteps in mind to protect your wardrobe investments:
- Assuming consistency across fabric types: A woven linen tunic in a size 1 will fit differently than a cotton-spandex knit pullover in the same size 1. Structured wovens offer zero give, so size up if your bust measurement sits at the top end of a size range.
- Ignoring pant rises: Chico's trousers come in pull-on, ankle, and tailored zip styles. Pull-on pants rely heavily on waist stretch, whereas tailored trousers with structured waistbands require strict adherence to your hip and high-waist measurements.
- Overlooking garment silhouette: Oversized boyfriend shirts and architectural ponchos are intentionally cut with excessive positive ease. Buying your exact numerical size in an intentionally oversized style might make the garment look sloppy rather than stylish. Check the product description for words like slim, tailored, or relaxed.
Frequently Asked Questions
What Chico's size should I buy if I normally wear a US size 10?
A standard US size 10 maps directly to a Chico's size 1. If you prefer a looser, more relaxed fit in unstructured tops, you can experiment with a size 2, but size 1 will give you the intended designer fit.
Do Chico's petite sizes use the same 000-to-4 scale?
Yes. Petite styles use the exact same numerical scale (00 to 3 or 4), but the garment dimensions are scaled down in length, rise, and sleeve proportions to fit frames 5'4" and under.
Why does Chico's use its own sizing system instead of standard numbers?
The proprietary sizing system is designed to reduce vanity sizing inconsistencies. By combining two traditional US sizes into a single number and engineering the garments with stretch and drape, the brand ensures a more consistent fit across different clothing categories.
How do I know if I need a size 00 or a size 000?
Size 000 is engineered for a traditional US size 0 or 2 with a very slender frame. If a US size 2 occasionally feels slightly loose or long in the shoulders, start with 000. If a US size 2 fits snugly, choose 00.
