Shopping plus size online opens up a much wider market than what's available in most physical stores nearby, but it also comes with extra risk: you can't try things on, and not every store that calls itself "plus size friendly" actually is. Here's how to navigate it more safely, step by step.
Before you buy: vet the store
Before entering your card details, check a few basics: does the site have a real contact email or support number, not just an anonymous contact form? Are reviews present across multiple platforms (not only on the site itself, where it's easier to filter them)? Does the site use a secure connection (the padlock icon in the address bar)? Another useful signal is complete legal information: business registration, physical address, and clear, easy-to-find terms of sale.
Size charts: the most important document on the page
Never trust the letter alone (S, M, L…): always look for the size chart in inches specific to that product or brand. If a site doesn't provide a detailed size chart, that alone is a signal it may not have invested in plus size fit. The best charts list at least three separate measurements (bust, waist, hips), not just one generic size covering the entire garment.
How to read fit-focused reviews
The most useful reviews mention the reviewer's height and measurements alongside a verdict on sizing ("I'm a size 18, ordered 18, runs big on the hips"). If a site displays these, give them more weight than a generic product description. Also pay attention to review dates: a store that changed suppliers or patterns might have older reviews no longer representative of current fit.
Payments and security
Prefer payment methods with some form of buyer protection (credit card, PayPal) over direct bank transfer, especially on stores you don't know yet. If a site only accepts wire transfer for large orders, treat that as a signal worth paying attention to. Also verify the site has a valid security certificate (the padlock in the browser bar) before entering any payment details.
Exchanges and returns: read before you order, not after
Before finalizing a purchase, always find out: how many days you have to return an item, who pays for return shipping, and whether refunds come as cash or store credit only. These details, more than anything else, determine how stressful the experience will be if the size doesn't work out. Some stores also offer free size exchanges without needing to ship back and reorder from scratch — worth factoring in when comparing two similar stores.
Shipping times and customs
If you're ordering from international stores, always check where the product actually ships from (sometimes different from the site's country) and whether customs fees apply on arrival. A seemingly lower price can end up costing more once duties and customs handling are added.
When it pays to wait for a sale
If a piece isn't urgent, waiting for an official sale (rather than the fake "always on sale" pricing some sites use year-round) lets you save money without falling for a false sense of urgency.
Building a list of stores you trust over time
Once you find a store that genuinely meets your criteria — clear size charts, verifiable reviews, easy returns — it's worth bookmarking it instead of searching from scratch every time. Over time you'll build a small personal list of trusted retailers, which drastically reduces the risk of an unpleasant surprise on your next order.
Customer service as an early trust signal
Before placing a larger order, try sending a simple question to customer service, something about fit or fabric, and see how quickly and specifically they respond. A store that answers promptly and knowledgeably before you've even bought anything is usually the same one that will handle a return or exchange well later if you need it.
The bottom line
A trustworthy plus size store online is recognizable by concrete signals: detailed size charts, verifiable reviews, secure payments and clear return policies. Checking these before ordering saves you time, money and frustration, and lets you actually enjoy the advantages of online shopping without its most common pitfalls.
In the CurvyIndex directory you'll find stores already vetted on these exact criteria, so you're always starting from a place of trust.
