A summer commuting suit for a partner who sweats easily was made in Cheil Industries Bonavito wool-blend navy fabric for ₩300,000-something, about half the ₩600,000–700,000 charged for ready-made suits at outlets. JJ Republic suits office workers after a daily work suit, not just wedding formalwear. ## Good to know - **Location**: 2F, 13 Gangnam-daero 152-gil, Gangnam-gu, Seoul (5-minute walk from Sinsa Station Exit 8) - **Hours**: Daily 11:00–20:00 - **Price paid**: ₩300,000s - **Fabric chosen**: Cheil Industries Bonavito wool blend, navy - **Price compared with**: Outlet ready-made suits at ₩600,000–700,000 - **Price reference**: ₩300,000 ≈ $223 · ₩600,000 ≈ $445 (2026-09-15) *as written by the visitor on Jul 19, 2026* A must-read if you're looking into custom tailoring in Gangnam! I saved half the price of a ready-made suit with JJ Republic's ₩300,000-something summer suit. ![Summer custom suit at JJ Republic Sinsa Main Store](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-01-p48of-1200.webp) ## Outlet ready-made suits at ₩600,000–700,000 vs. a custom suit in the ₩300,000s My partner urgently needed a cool, light summer suit for the daily commute. Last weekend we went to a nearby outlet to buy something ready-made! Even at the outlet, the moment the fabric felt a little nicer or the fit looked good, the price jumped straight past ₩600,000–700,000 basically by default ㅠㅠ It felt like such a waste to pay that much for something off the rack...!! ![Interior of the Gangnam custom tailoring shop](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-02-1a71k-966.webp) I asked around like crazy among people I know, and they recommended JJ Republic, a Gangnam custom tailor known for cutting out the factory distribution process entirely, so the price bubble is gone while the quality is on par with department store brands — a great value tip. After going, I understand why everyone praises it. Let me share my fitting review with the Cheil Industries Bonavito fabric 🤍 ![Interior space of JJ Republic Sinsa Main Store](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-03-u5ls5-966.webp) ## Where is JJ Republic Sinsa Main Store, and what are its hours? JJ Republic Sinsa Main Store is a 5-minute walk from Sinsa Station Exit 8, located at 2F, 13 Gangnam-daero152-gil, Gangnam-gu, Seoul. It's open daily from 11:00 to 20:00. ![Consultation area of the custom tailor near Sinsa Station](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-04-68sly-966.webp) ## Why a ₩300,000s custom suit is fair value in Gangnam There's usually this preconception that custom suits must be super expensive, right? JJ Republic Sinsa runs its own production line factory directly, so they say outsourcing costs and middleman margins are basically eliminated. ![Sample custom-tailored suits hanging in the store](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-05-1a15j-966.webp) On top of that, they haven't partnered with wedding planners, so there's no unnecessary referral commission either — which means they can offer high-quality tailoring at a surprisingly great value of just ₩300,000-something! It's great not only for pricey formalwear but also for office workers like me who need a suit to wear to work every single day. ## One-on-one fabric and detail consultation at JJ Republic ![Summer fabric swatches laid out during the one-on-one fabric consultation](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-06-1rmpn-966.webp) The consultation process itself was genuinely touching! My partner sweats a lot, so I asked mainly for the lightest, coolest summer suit options. The staff member laid out summer fabrics by color that were breathable and resistant to wrinkling, and honestly compared the pros and cons of each sample one by one. We picked the Cheil Industries Bonavito wool-blend fabric!! ![Cheil Industries Bonavito wool-blend navy fabric](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-07-14y9l-966.webp) The final color we chose was navy — the most versatile yet sophisticated option. There were plenty of sample suits made for other customers displayed in the store, so we could immediately check what the fabric would look like in real life, which made choosing so much easier. ![Sample suits on display in the store](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-08-1oelx-966.webp) From the width of the lapel to the sleeve design, lining, and buttons, there was real fun in customizing every detail myself. ## How careful is the fit measurement? ![Scene of custom suit measurements being taken](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-09-w1u22-m-966.webp) The real reason to insist on custom tailoring over ready-made is that perfect fit tailored exactly to your body, right? Once the fabric and design were decided, we moved on to the actual measuring, and the staff member very meticulously checked my partner's shoulder width, chest, waist, and arm/leg length. My partner's hips are a little on the wider side, and they picked up on that specific detail and adjusted the fit accordingly. ![Checking the shoulder and waist fit adjustment](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-10-1h3xn-966.webp) It wasn't just about measuring clothing size — they even took into account usual styling habits and the intended purpose of the suit. Seeing how thorough they were, I understood why everyone goes out of their way to find a custom tailor in Gangnam. ![Fit of the finished navy summer suit](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-11-1ko9t-966.webp) After paying ₩600,000–700,000 at the outlet and still being left with things to be unhappy about, getting a quality suit tailored to my body for half that price, ₩300,000-something, felt really great ..♥️ ![Button samples available to choose from](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-12-1tolu-966.webp) ![Ties displayed in the store](https://img.superchart.com/images/sinsa-custom-suit-summer-navy-jj-republic/sinsa-custom-suit-summer-navy-jj-republic-13-rnjad-966.webp) You can even choose the buttons and tie haha ## Final verdict on JJ Republic Sinsa Main Store If you're planning to get a custom suit made in Gangnam, definitely visit JJ Republic. My partner says the suit is light and the fit is so nice that he's been wearing it almost every day like a uniform!! A lot of people come here to prepare men's wedding suits, but I'd also recommend it to anyone like us looking for a suit to wear daily in everyday life! ## Where it is - JJ Republic Sinsa Main Store (제이제이리퍼블릭 신사본점) - 2F, 13 Gangnam-daero152-gil, Gangnam-gu, Seoul, South Korea - 서울특별시 강남구 강남대로152길 13 2층 - 37.5173452, 127.0205317 - Google Maps: https://www.google.com/maps/search/%EC%A0%9C%EC%9D%B4%EC%A0%9C%EC%9D%B4%EB%A6%AC%ED%8D%BC%EB%B8%94%EB%A6%AD%20%EC%8B%A0%EC%82%AC%EB%B3%B8%EC%A0%90/@37.5173452,127.0205317,17z --- Superchart · https://superchart.com/en/@seoul-lunch-routes/sinsa-custom-suit-summer-navy-jj-republic/ · https://superchart.com/llms.txt
