Matching sets are the laziest and best outfit choice, and Z Supply has at least a dozen. Here’s which ones are actually matchy and which miss the assignment.
I own two full Z Supply sets and I’ve tried on a third. They’ve been through enough wear to speak to the real question every buyer has: does the top actually match the bottom, and does the sizing work across both pieces without creating a weird proportion problem? Z Supply’s loungewear-leaning catalog is a core reason the brand shows up in our Affordable Fashion Brands roundup, and the matching sets are their most purchased category for a reason. My longer Is Z Supply Worth It? covers the brand overall; this is the zoomed-in set-specific version.
The Z Supply Set Lineup
Z Supply sells sets in three broad categories that rotate through the catalog. There are rib-knit sets (close-fit tank and short or legging pairs in matching rib fabric), slub knit sets (looser fit, nubby texture, usually a boxy tee with matching shorts or wide-leg bottoms), and gauze or linen sets for the warmer months (drapey shirts with matching pants, strongest in the spring catalog). Dedicated pajama sets are a separate category — not the same as the loungewear sets — and I’d point you to a pajama-specific review if that’s what you want rather than conflating the two.
The sets are usually sold as top and bottom separately, so you pick each size independently. This sounds like an advantage and it is — you can mix a medium top with a small bottom if your proportions need it — but it’s also where most of the set-buying mistakes happen, because buyers assume a “small” in the top will match a “small” in the bottom and that’s not always true.
The Matching Problem: Fabric and Dye Consistency
Here’s the honest issue with Z Supply sets. The top and bottom are usually cut from the same bolt of fabric at the factory, which means the color and fabric weight match out of the bag. Wash them a few times, though, and the color can drift apart slightly — especially on darker colors where one piece gets slightly more wear than the other. My rib set in black has held its color perfectly on both pieces after ten washes. My slub set in a sage color has drifted a little — the top is marginally lighter than the bottom now because I’ve washed the top more often.
This isn’t a defect; it’s physics. Any time you have a matching set where one piece gets washed more, the colors drift. The fix is to wash both pieces together in the same load, even if only one is dirty, to keep them in sync. Buyers who treat the pieces as independent end up with mismatched colors after a few months. Buyers who wash them together keep the match.
Sizing Across Top and Bottom
Z Supply’s sizing is generally consistent across the top and bottom of the same set, but the rib sets run tighter than the slub sets. I wear a medium in both my sets, but the rib feels noticeably more fitted than the slub. If you’re between sizes, size up on rib and stay true on slub.
The pants or shorts in a set tend to run slightly more forgiving than the top — more stretch in the waistband, more drape through the leg, more room for a half-size adjustment. The top is where the fit problem usually lives. If your bust doesn’t match your hip by standard sizing math, buying top and bottom in different sizes is the move, and it’s worth doing.

The Sets Worth Buying
The rib tank plus rib shorts set in a neutral color (black, oat, white) is the best-value Z Supply set and the one I recommend first. It’s the most versatile piece in the category — it reads as loungewear at home, as a casual summer outfit out of the house, and the rib fabric is the most durable in the set lineup. Both pieces hold up through the wash cycle as well as any Z Supply basic.
The slub knit relaxed tee with matching shorts is the second pick. It’s less versatile (reads more as loungewear than street-wear) but it’s more comfortable for long days at home, and the slub fabric is the most forgiving of body shape variation. Buy this one if you want a set you’ll actually relax in.
The Sets to Skip
The gauze and linen sets look beautiful on the hanger and lose half their appeal after one wash. The drape softens, the color shifts, and the proportions go slightly off. For the price, these are not worth it unless you’re specifically buying for a summer vacation and you don’t need long-term rotation value. Photograph well, don’t wear well.
Anything in a bold print or saturated color goes on deep discount within one season. Wait for the sale or don’t buy.
The Verdict
Z Supply sets are worth the purchase if you pick the rib or slub silhouettes in neutral colors and wash top and bottom together to keep the match. They’re solid loungewear-to-street crossover pieces at a reasonable price. Skip the gauze and linen sets unless you’re buying for a specific trip and you don’t need long-term durability. Skip bold colors and prints at full price.

FAQ
Do Z Supply sets actually match?
Yes, out of the bag — both pieces are cut from the same fabric bolt. Over time, they can drift slightly in color if you wash one piece more than the other. Wash top and bottom together in the same load to keep the match consistent.
Are Z Supply sets true to size across top and bottom?
Generally yes, but the rib fabric runs tighter than the slub. Between sizes, size up for rib and stay true for slub. The bottom tends to run slightly more forgiving than the top; if your bust and hip don’t match standard sizing, buying the pieces in different sizes is legitimate.
Can you wear Z Supply sets as separates?
Yes, and this is arguably the best argument for buying them. The rib and slub pieces especially work as standalone items in your wardrobe, not just as matching sets. Buying a set effectively gives you two useful pieces that can also be worn together.
