The Plus-Size Style Guide We Wish Existed

Posted by the Kothlis team · 8 min read

Most plus-size shopping advice is written by people who have never worn a size 18. So let's start over. This is the only plus-size style guide you need to bookmark: a real, no-nonsense breakdown of what fits, what to skip, and how to actually build a wardrobe you'll wear instead of hide behind.

1. Stop shopping for the body you think you should have

The single biggest mistake we see customers make: ordering a size down because they're "working on it." Buy for the body you have right now. The piece will either feel like a hug or a punishment — there is no in-between.

If you're between sizes on Kothlis, the rule is simple: size up for structured fabrics (denim, blazers, jumpsuits), stay true to size for stretch (jersey, knit, sweatshirts). Check the size guide on every order — our fits vary slightly between silhouettes.

2. The four silhouettes that work for almost every plus body

You don't need 40 different shapes in your closet. You need these four, in a fabric you like:

• Wide-leg pants. Balance proportion, hide nothing, look intentional. Our Bottoms collection leads with this for a reason.
• A puff- or balloon-sleeve top. Visual weight up top draws the eye away from the midsection without the apologetic billow of a tunic.
• A midi or maxi with a defined waist seam. The waist seam is the trick — not shapewear. See the Dresses collection for our edit.
• One real layering piece. A boyfriend blazer, an open-knit cardigan, or a denim shacket. One good outer layer makes everything else in your closet 30% more wearable.

3. Color: stop wearing only black

The plus-size industry trained an entire generation to hide in black. We're done with it. Black is fine. So is rose, sage, cobalt, butter yellow, and any other color you've been told is "too much for your size."

If you're nervous, start with one bold piece per outfit: a printed dress with neutral shoes, or a bright top with classic denim. The contrast does the work.

4. The five fabrics worth paying for (and the ones to skip)

Worth it:

• Linen and linen blends for summer — breathes, drapes, doesn't cling.
• Ponte knit for pants and structured dresses — holds shape, forgives lunch.
• Cotton-modal jersey for tees — softer than 100% cotton, doesn't pill after three washes.
• Heavyweight French terry for sweatshirts — looks expensive even when it isn't.
• Stretch denim with 2% elastane — the magic number. Less, and you can't move. More, and they bag out by lunch.

Skip:

• 100% polyester anything that touches your skin.
• "Slinky" satin — it amplifies every line you weren't trying to amplify.
• Crepe with no stretch — looks great on the hanger, performs terribly on a real body.

5. The fit details we look for on every Kothlis piece

When we curate a new style for the shop, we check the same five things every time:

1. Bust dart placement. If the dart points anywhere other than the apex of your bust, the fit will pull weird across the front.
2. Arm hole depth. A too-tight armhole on a tank is a dealbreaker — it doubles every roll under your arm. We size up.
3. Waist seam height. For dresses, the waist seam should hit just above your natural waist, not on it. Higher = longer-looking legs.
4. Hem weight. Maxis and midis need either a weighted hem or a structured fabric, or they cling.
5. Crotch curve on bottoms. The single most-ignored fit point in plus-size manufacturing. If a brand gets this right, they get everything right.

6. One last thing

You don't need to earn the right to wear what you want. You don't need to lose weight first, or save the dress for an event, or buy "flattering" instead of fun. Wear it now. Take the photos. Take up space.

That's why Kothlis exists.
