The Sabine brings instant structure and quiet elegance to any outfit it joins. Gently shaped through the waist, it defines your silhouette while leaving comfortable, easy movement — the fitted blazer that looks professionally tailored the moment it goes on, whether you are heading into the office or meeting friends for a long lunch. Structure is the fastest shortcut to looking intentional, and a good blazer is structure you can throw on in five seconds.
A clean single-button front and classic lapels keep the look refined with absolutely no fuss, and the lightweight build makes it genuinely wearable from morning to night rather than a jacket you shed by noon. It pairs beautifully with jeans, tailored trousers, or dresses, moving smoothly from daytime plans into evening ones without missing a step. It earns compliments without ever demanding maintenance in return.
From Kessoro, the Sabine comes in women's sizes S through 3XL across versatile, easy-to-match colors. A well-made blazer is one of the most reliable pieces a wardrobe can hold, and this one is designed to earn that spot for years — timeless lines, dependable comfort, and the quiet confidence of always having something elegant ready to put on. Every capsule wardrobe starts with a blazer like this one.
- Tailored waist: gently shaped, flattering fit
- Single-button front: clean closure with classic lapels
- Lightweight wear: comfortable from morning to night
- Versatile styling: jeans, trousers, or dresses
- Sizes: S–3XL
Size guide
Kessoro garments are cut to US sizing. The charts below are body measurements — measure yourself, then pick the size your measurements fall into. They are not the flat measurements of the garment itself.
How to measure
- Chest / bust — around the fullest part, keeping the tape level under your arms.
- Waist — around your natural waist, the narrowest point, usually just above the navel.
- Hips — around the fullest part, roughly 8 inches below the waist.
- Inseam — from the crotch seam to the bottom of the ankle.
Keep the tape snug but not tight, and measure over light clothing or bare skin.
Women's sizing
| Size | US | Bust (in) | Waist (in) | Hip (in) |
|---|---|---|---|---|
| XS | 0–2 | 31–32 | 24–25 | 34–35 |
| S | 4–6 | 33–34 | 26–27 | 36–37 |
| M | 8–10 | 35–36 | 28–29 | 38–39 |
| L | 12–14 | 37–39 | 30–32 | 40–42 |

| 2XL | 20–22 | 43–45 | 36–38 | 46–48 |
Men's sizing

|---|---|---|---|
| S | 35–37 | 29–31 | 14–14½ |
| M | 38–40 | 32–34 | 15–15½ |

If you're between sizes
Size up. This is the single most common piece of advice we give. It applies especially to:
- Knitwear, sweaters and cardigans, which are cut closer than you might expect.
- Anything described as slim-fit or tailored.
- Outerwear you plan to layer over a shirt or sweater.
If you prefer a relaxed or oversized look, size up regardless of where your measurements land.

Real, verified reviews from people who wear Kessoro.
I screamed when I opened this - the packaging was gorgeous and the piece inside was even better. Exactly what I ordered, true to size, and the quality is incredible. Already planning my next purchase.
Finally found a brand that gets elevated basics right. Everything feels premium without that ridiculous markup. The fabric on this is so soft and the fit is genuinely flattering. Will be back for more.
Bought this for a work trip and got so many compliments. Clean, well-fitted, and the material holds up all day without wrinkling. Kessoro is my new go-to for business casual.
The color is even better in person than the photos, which never happens. Fits beautifully, shipped faster than expected, and the returns process was super easy when I needed to swap a size. Love this brand.
I'm very picky about quality and Kessoro delivered. The stitching is clean, the fabric is substantial, and it washes perfectly. I've bought from a lot of online brands and this is one of the few that actually matched the photos.
Ordered two pieces and both arrived beautifully packaged and exactly as described. The sizing is spot on — I'm usually between sizes and went with the recommendation in the size guide, which was perfect.
Needed something sharp for a dinner out and this delivered. Looked expensive, wore comfortably all evening, and held its shape. Already told three friends about Kessoro. Solid brand.
As someone who struggles to find things that fit well off the rack, I was shocked at how perfectly this fit. True to size, great length, and the material doesn't cling. I've already ordered two more colors.
Super impressed with the quality for the price. I've paid twice as much for less at other stores. The fabric feels premium, shipping was fast, and customer service responded to my question within hours. 10/10.
I bought this as a gift for my daughter and she absolutely loves it. The quality is evident from the moment you open the box. Classic, elegant, and beautifully made. Kessoro has a new loyal customer.
