How to reduce fashion returns during Black Friday and Cyber Monday

Most Black Friday planning goes into traffic and conversion. Returns get planned for afterward, once the boxes start coming back. That order is backward for fashion specifically, because the return rate on a sale weekend is not a fixed cost. A large share of it comes from the same fixable problem year round: the shopper could not tell how the item would actually fit.

Why do fashion returns spike during Black Friday and Cyber Monday?

Three things happen at once during a big sale weekend that do not happen on a normal Tuesday. Order volume jumps, so the raw number of returns jumps with it even if the rate stayed flat. A meaningful share of those orders are gifts, bought for someone whose exact size the buyer is estimating. And the deal pressure itself pushes people to decide fast, which for clothing usually means ordering more than one size just in case.

None of that is unique to Black Friday. It is the same fit-uncertainty problem fashion has all year, just compressed into a shorter window with more orders moving through it.

When is Black Friday and Cyber Monday in 2026?

Black Friday is November 27, 2026, the Friday after Thanksgiving. Cyber Monday is November 30, 2026. Most fashion brands run their sale across the entire stretch, sometimes starting the week before, so the return spike is not a single weekend either. It builds through late November and lands hardest in the two to three weeks after Christmas, once gifts get opened and tried on for real.

• Thanksgiving: November 26, 2026
• Black Friday: November 27, 2026
• Cyber Monday: November 30, 2026
• Peak return window: typically the last week of December through mid January, once gifted items are opened and tried on

What actually drives the extra returns?

Discount pricing removes the natural brake on ordering a backup size. When a jacket is 30 percent off, buying it in two sizes to be sure feels cheap, even though it doubles the shipping and restocking cost on the retailer's side. Add gift buying, where the purchaser is not the person who will wear the item, and the odds of a wrong-size order climb further.

1. Sale pricing lowers the cost of guessing. A discounted item makes ordering two sizes to keep one feel low risk to the shopper, even though it is not low cost for the store.
2. Gift purchases remove the one signal that normally helps. The buyer cannot try anything on themselves, and often does not know the recipient's exact size in that specific brand.
3. Compressed decision time favors backup ordering. A shopper moving fast through a 48 hour sale window defaults to the safe choice, which for clothing is ordering more than they need.

How can a fashion store prepare before the sale starts?

The fixes that matter most are the ones already in place before traffic arrives, not the ones added while a customer is on the return line with support.

• Tighten size charts and fit notes now. A vague size chart causes more guessing during a high-volume weekend than it does on a quiet Tuesday, simply because more people are relying on it at once.
• Add real customer photos to reviews where you can. A photo of the item on a real body does more to answer the fit question than another paragraph of copy.
• Give shoppers a way to preview fit before checkout. This is where virtual try-on does its job: a shopper uploads or captures a photo, sees the item on themselves, and has one less reason to order a second size just in case.
• Test any new tool weeks ahead, not during the sale. Install and verify a catalog sync in October or early November, so Black Friday traffic is not the first real test of a new feature.

Where does virtual try-on fit into a Black Friday returns plan?

Corlen adds a try on button directly to your Shopify product pages, so a shopper deciding between two sizes during a sale can actually see the difference on their own body instead of guessing. That preview runs at the exact moment the wrong choice usually gets made: right before checkout, under time pressure, often for a gift the buyer will not wear themselves.
