Blissy Silk Pillowcase vs Slip: Is Cheaper Better?

The Blissy silk pillowcase vs Slip question sounds like a luxury standoff, but the silk itself is nearly the same on both. Both are 100% mulberry silk woven to 22 momme, the weight that gives silk pillowcases their cool, slippery feel, and both promise less frizz and fewer sleep creases.

So the real fight is everything around the fabric. The Blissy pillowcase runs about $106 for a queen, ships with a hidden zipper, and carries OEKO-TEX certification. Slip is the celebrity-and-Vogue darling that costs more and leans on its reputation.

For this comparison we read both brands’ spec pages, checked their certifications and return policies, and weighed buyer reviews across retailers. We didn’t sleep on them in a lab, so every claim below is sourced to the makers or to owners.

The short version: if you want the recognizable fashion name, Slip delivers it. If you want the same 22-momme silk for less money with better paperwork, Blissy is the smarter buy, and here’s exactly where it wins.

Blissy vs Slip at a glance

What each one actually is

The Blissy pillowcase is 100% mulberry silk at 22 momme, which the brand lists as grade 6A, the top mulberry grade. Every adult size uses a hidden zipper so the case stays put, and it’s OEKO-TEX certified, meaning the fabric is tested for harmful substances. A queen runs about $106, with a frequent buy-three-get-one promo, and it’s now sold in around 1,800 Target stores as well as direct.

Slip is the original luxury name here. Its silk is the same 22-momme mulberry, sold under the slipsilk trademark, and it comes in both an envelope-style Original and a zippered version.

It’s the brand with the fashion-magazine resume: a Vogue “best silk pillowcase” nod and an Oprah Daily Editor’s Choice, plus a long list of celebrity fans. A queen typically costs $120 to $125.

So the honest framing is this. On the silk, they’re twins. Blissy is the value-and-certification play; Slip is the prestige play. That difference decides most of the rounds below.

Round by round

Price and value

Round winner: Blissy Silk Pillowcase

No suspense here. Blissy is cheaper at every size, and it isn’t close on a king.

A Blissy queen runs about $106 versus roughly $120 to $125 for a Slip queen, and the gap widens on kings, where Blissy’s $109.95 undercuts Slip’s $147 to $158 by around forty dollars. Blissy also runs a buy-three-get-one-free promo that Slip doesn’t match.

When the silk is the same weight and grade, price does real work. For a whole-bed set, choosing Blissy can save the cost of an extra case or two. This round is settled.

The silk itself

Round result: Tie

This is the round everyone expects to be decisive, and honestly, it’s a draw.

Both pillowcases are 100% mulberry silk at 22 momme, the sweet-spot weight that feels cool and smooth without being flimsy. Owners of both describe the same soft, slippery “sleeping on a cloud” feel, less frizz in the morning, and fewer sleep lines.

Blissy states a 6A grade and adds OEKO-TEX certification, which is a genuine plus on paper. But in the hand and against your cheek, these two are as close as silk pillowcases get. Calling a winner on feel alone would be inventing a difference that isn’t there.

Closure and staying put

Round winner: Blissy Silk Pillowcase

A small detail that matters more than it sounds: how the case stays on the pillow.

Blissy puts a hidden zipper on every adult size, so the silk stays snug and can’t creep off as you move. Slip’s signature Original uses an envelope closure, which looks clean but can slide loose on a firm or overstuffed pillow.

Slip does sell a zippered version too, so you can match Blissy if you pick that model. But zipper-as-standard is the more foolproof default, and for restless sleepers it’s the safer choice. Blissy takes it.

Brand prestige and reputation

Round winner: Slip Silk Pillowcase

Here’s where Slip earns its premium, and it’s a real, fair win.

Slip is the established luxury name, with a Vogue “best silk pillowcase” mention, an Oprah Daily Editor’s Choice, and a following among celebrities that has made it a fixture on beauty gift guides for years. If you want the pillowcase people recognize, that reputation is worth something.

Blissy is huge in its own right and increasingly mainstream, but it’s the direct-to-consumer challenger, not the fashion-house original. On pure prestige and editorial pedigree, Slip is the one with the resume, and this round is fairly its own.

Guarantee and where to buy it

Round winner: Blissy Silk Pillowcase

On buying confidence, Blissy gives you more room to change your mind.

Blissy backs its cases with a 60-day money-back guarantee, double Slip’s 30-day window, and it’s widely stocked through Target, Amazon, Walmart and Macy’s if you’d rather buy in person. Slip counters with free return shipping, which is a genuine perk Blissy doesn’t always offer.

Still, twice the return window plus broad retail availability is the stronger safety net for a first-time silk buyer. If you’re nervous about spending three figures on a pillowcase, the longer guarantee tips it. Blissy takes the round, and the matchup.

What owners say

Both brands have devoted followings. Blissy sells a very large volume of cases and draws steady praise for the soft feel, cooler sleep and less morning frizz, with the recurring complaints being price and the occasional zipper or seam issue. Because it sells so widely, buying from Blissy or an authorized retailer matters, since counterfeits float around third-party marketplaces.

Slip’s reviews echo the same softness and add years-of-washing durability, and its retail ratings are strong where samples are large, including a 4.8 out of 5 across 464 ratings on one major retailer’s queen listing. Its common gripes are the price and, for the envelope Original, slipping off the pillow.

With any silk pillowcase, the benefits are about friction and comfort, less frizz and fewer sleep creases, rather than a medical treatment for skin or hair. Set expectations there and both brands deliver.

Pros and cons of choosing Blissy over Slip

Who should buy which

Buy the Blissy silk pillowcase if you want the same 22-momme mulberry silk for less, plus OEKO-TEX certification, a secure hidden zipper and a longer guarantee. For the value-minded shopper who cares about the sleep, not the label, that’s the pick, and it’s why Blissy wins here.
