How to Spot Authentic CSB Leggings Before You Buy

With the rise in popularity of CSB (Cute Seamless Basics) leggings, it’s no surprise that counterfeit versions have begun to appear in online marketplaces and even some retail stores. While imitation may be a form of flattery, fake leggings often lack the comfort, quality, and performance of the real deal. If you want to invest in authentic CSB leggings, knowing how to tell the difference is essential.

Here’s a complete guide on how to spot real CSB leggings before you make a purchase.


1. Check the Official CSB Logo and Branding

Authentic CSB leggings feature a clean, minimalist logo that’s either heat-pressed or subtly embroidered. Watch out for the following:

  • Incorrect fonts or spacing in the logo
  • Misplaced logos, such as those found near the knees or calves (CSB typically places their branding near the waistband or back center)
  • Poor-quality printing that easily peels or fades

Always cross-reference with images on CSB’s official website or verified retailers.


2. Feel the Fabric Quality

One of CSB’s strongest selling points is its buttery-soft, high-stretch fabrics. Authentic CSB leggings use seamless, moisture-wicking materials that are supportive but still breathable. Red flags include:

  • Fabric that feels rough, plastic-like, or overly shiny
  • Seams that are bulky, uneven, or irritating to the skin
  • Thin material that becomes sheer when stretched (most genuine CSB leggings are squat-proof)

If possible, compare the feel to a pair you know is real or read verified reviews carefully.


3. Inspect the Stitching and Construction

Authentic CSB leggings are seamless or nearly seamless, with flatlock stitching designed to prevent chafing. Here’s what to look for:

  • Clean, even seams with no loose threads
  • No bulky inner labels—CSB typically uses tagless or printed size information
  • Smooth, sculpted fit that hugs the body without sagging or bunching

If you notice sloppy construction or rough seams, it’s likely not authentic.


4. Purchase from Verified Sellers

Your best bet to avoid counterfeits is buying from authorized retailers or directly from CSB’s official website. Avoid third-party sellers on platforms like:

  • eBay
  • Poshmark (unless verified as new with tags)
  • Marketplace sites without clear product origin

Look for confirmation emails, receipts, or a digital paper trail that proves the source is legitimate.


5. Compare Prices Cautiously

CSB leggings are premium products—if the price seems too good to be true, it probably is.

  • Be wary of deep discounts (e.g., $10 leggings labeled as CSB when the retail price is usually $40–$60)
  • Cross-check discounts with CSB’s current sales to see if they align
  • Avoid “bulk sales” or random sellers offering multi-packs of “CSB” leggings

6. Review Customer Feedback

Before buying from a new site or seller, read customer reviews. Pay attention to:

  • Complaints about poor fit, itchy fabric, or strong chemical smells
  • Mention of items arriving without tags or in generic packaging
  • Inconsistent sizing (authentic CSB leggings follow a well-defined size chart)

Real buyers often leave clues that can alert you to fakes.


7. Look at the Packaging

CSB typically ships its products in branded, eco-friendly packaging with size stickers, product names, and sometimes QR codes. Fake versions may come in:

  • Generic plastic bags
  • Packaging with typos or distorted logos
  • Unsealed, unbranded wrap

Pay attention to these small details—they say a lot about product authenticity.


Final Tips for Buying Authentic CSB Leggings

  • Stick to trusted sources: CSB’s official website, authorized boutiques, or major retailers
  • Ask questions if buying secondhand: request photos of tags, packaging, and receipts
  • Know what real CSB looks and feels like—education is your best defense against counterfeits

By following these tips, you’ll ensure you’re investing in real CSB leggings that deliver the comfort, quality, and style the brand is known for. Don’t settle for less—your wardrobe (and wallet) will thank you.
