Groom's wedding suit tailored in Gangnam for ₩599,000: JJ Republic

In short

JJ Republic Sinsa Main Store is a made-to-measure suit shop near Sinsa Station Exit 8 in Gangnam, Seoul, with its own tailoring factory on site. Preparing for a wedding, the writer ordered a groom's suit in dark grey Jeil Mojik First Class 100% wool and skipped the mid-fitting so JJ Republic could finish in time for the photoshoot. The Super Promotion brought the whole suit, tie included, to 599,000 won — a sharp classic fit for far less than most groom's suits.

Groom's suit tailored at JJ Republic Sinsa Main Store

One of the biggest worries when we started wedding prep was the groom's suit. I normally dress pretty casually for work, so spending millions of won on a Gangnam custom suit for the wedding felt like a lot of pressure. While looking around for a good place to tailor a groom's suit, I found JJ Republic Sinsa Main Store — a Gangnam custom suit shop with great value for money!

Where is JJ Republic Sinsa Main Store, and where do you park?

Store entrance on the 2nd floor of a building near Sinsa Station Exit 8

Coming out of Sinsa Station Exit 8, you go past the pharmacy right in front of you, turn into the alley, and take a left — the shop is on the 2nd floor of the building across from the CU convenience store, so it wasn't hard to find. If you're driving, there's free parking in the alley to the right of the building, and free valet in front of Cheonmimi Chinese restaurant on the left. Right in the middle of Gangnam, it's super accessible by public transit too, and since the Sinsa branch is directly operated (not a franchise), that gave me more confidence.

What was really great was that JJ Republic Sinsa has its own in-house tailoring factory right inside the store. Cutting out the unnecessary markup from the usual distribution process keeps prices reasonable, and the turnaround — usually 3-4 weeks or more elsewhere — averages just 7-10 days here. Huge advantage ✨

Inside JJ Republic: the consultation room and on-site tailoring factory

Store interior with consultation table and organized fabric sample books

Walking in at our reserved time for the groom's suit consultation, there was a consultation table all set up. Off to one side, neatly separated, was the actual factory area where the suits are made +_+ The consultation space had fabric sample books organized by type, and being able to see transparently how high-quality fabric becomes a suit in the factory really boosted my trust in the place.

Wall lined with finished custom suits

Since this place is well known for men's tailored formalwear, one whole wall was packed with finished suits waiting for their owners! Seeing the trace of so many people who'd already made their choice here made me commit to the contract without hesitation 👍

Choosing the fabric: dark grey Jeil Mojik First Class 100% wool

We'd made a Naver Reservation in advance, and I liked that the custom suit prices were listed transparently on Naver. At first we planned to go with the cheapest fabric option for the best value haha, but once we actually touched the fabrics and compared the colors in person, the 100% wool domestic Jeil Mojik First Class fabric felt far more luxurious and classic than the cheapest option! Seeing and feeling it with our own hands, the firm, refined tone of the Jeil Mojik First Class fabric won us over, so we finally settled on the dark grey color!

From the buttons to lapel size, pocket square shape, pocket details, and even the one-tuck style and rise length my fiancé had wanted, everything was carefully tailored to our preferences one by one. This is what makes a custom-tailored suit worth it, haha.

Picking up the finished groom's suit

We had a tight photoshoot schedule, so when we asked, they made it a day or two faster than the usual turnaround for a custom groom's suit! There was no mid-fitting process at all — once it was done, we booked a Naver pickup reservation, came in, and tried it on. The lines held a beautiful shape without being too tight — a perfectly classic fit ..🤍

The subtle, luxurious sheen when actually worn was amazing — even more than it looked as a fabric sample! It was tailored with a bit of room to spare, so my boyfriend was thrilled thinking he could still wear it for a long time even if he gained a little weight, haha.

What a Gangnam custom suit costs: ₩599,000 with a tie

With JJ Republic's Super Promotion applied, we got a groom's suit tailored with a tie included for a ridiculous 599,000 won Gangnam custom suit price! And on top of that, as a free gift, they threw in an elegant patterned black silk tie from their range that would look perfect for the photoshoot.. ✨

I've heard groom's suit prices usually start at 1-2 million won, but we got a suit that fits like a glove at a reasonable price. If you're looking for a groom's suit in Gangnam that nails both value and quality, I highly recommend booking a consultation at JJ Republic Sinsa Main Store!
