Gangnam tailor shop, ₩300,000s summer suit: JJ Republic Sinsa

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.

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...!!

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 🤍

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.

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.

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

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!!

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.

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?

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.

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.

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 ..♥️

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!
