That’s So Fetch Sizing Guide 2026: Get It Right

Ordering trend pieces online is a gamble when you cannot try them on, and That’s So Fetch is no exception. This That’s So Fetch sizing guide is built to take the guesswork out of your first order, using the brand’s own size charts and how different fabrics behave. If you have been burned by a dress that arrived too tight or a top that swallowed you whole, read this before you check out.

How That’s So Fetch Sizing Works

That’s So Fetch is an Australian boutique that ships to the US, so the fit follows Australian sizing conventions rather than standard US numbers. The brand states that it does its best to keep every outfit true to size, but it also acknowledges that each garment can fit slightly differently depending on the fabric and the cut. The most useful habit you can build is checking the size chart on each individual product page instead of assuming your usual size carries across the whole store.

Where the Kw Applies: Reading the Product Notes

The single most helpful part of any That’s So Fetch sizing guide is knowing that the brand flags fit issues directly in the product description. When a specific piece runs smaller or larger than a standard fit, That’s So Fetch adds a recommendation right there on the listing. That means you should never rely only on the general chart. Scroll down, read the description in full, and look for phrases like “we recommend sizing up” before you commit.

Style-by-Style Fit Tendencies

Because fabric drives fit, it helps to think by category rather than by a single number:

• Bodycon and party dresses: These use stretch fabrics that cling. If you are between sizes or want more comfort, sizing up is the safer call.
• Formal and maxi dresses: Structured or woven materials have less give, so a true-to-chart measurement matters more here.
• Lounge and activewear: These tend to be the most forgiving, so your standard size usually works.
• Tops and going-out pieces: Cropped and fitted cuts are common, so check the length measurements, not just the bust.

The brand also emphasizes a wide range of sizes, so the chart typically spans more options than a quick glance suggests.

Measure Yourself First

Guessing your size defeats the purpose of a chart. Grab a soft tape measure and record your bust, waist, and hips, then match those numbers to the listed centimeters or inches on the page. Compare against a garment you already own and love. This two-minute step is the difference between one confident order and a return cycle that eats into shipping time.

When to Size Up or Down

As a rule of thumb, size up if you prefer a relaxed fit, if the fabric is described as non-stretch, or if the product note warns the item runs small. Size down only when a listing explicitly says a piece runs large, since going smaller on stretch fabric can leave a dress unwearable. When you are truly between two sizes and there is no product note, defaulting to the larger option is usually the lower-risk move for dresses.

Final Tips Before You Order

Do a quick sanity check: confirm the chart on the exact product, read the full description for fit flags, and account for shipping from Australia so a return would not leave you empty-handed before an event.
