Great Fit and Perfect for Formal Events
Color: Black, Size: 30
I was really impressed with this MOGU slim-fit tuxedo. The jacket and pants fit surprisingly well right out of the box, and the material looks sharp without feeling cheap. It’s comfortable to wear and has a clean, modern look that works great for weddings or formal events. For the price, it’s an excellent suit set that delivers both style and value.

Great Suit, Fits Good and Very Comfy
Color: Navy, Size: 44, Color: Navy, Size: 44
I bought the MOGU Suit 2 piece slim fit suit kinda last minute for an event, and honestly I was suprised by how good it came out. The quality is better than I expected for the price. The fabric feels smooth and not cheap or itchy. The fit was pretty good overall. The jacket sits nice on the shoulders and the sleeves lenght was just a little bit longer than I like, but not a big deal. The pants fit slim but not tight, so I could move around without feeling uncomfortable. I think the sizing is mostly true, but if you're between sizes go up one. The stitching was actually clean and neat. I checked the seams because I’ve had suits before where threads be sticking out everywhere, but this one was solid. No loose ends, no weird cuts. Comfort wise, it’s suprisinly good. I wore it for hours and it didn’t feel heavy or rough. The one-button blazer gives it a nice modern look too. Overall, good buy for the money. Not a high-end designer suit, but for the price range it’s really good and looks way more expensive than it is. I’d definetly order again.

Just basted together
Color: Orange, Size: 30, Color: Orange, Size: 30
At first, I was super excited and thought it was a fantastic deal. I bought this suit for a work event, and got it a few days early. I tried it on, everything fit well, I loved the fabric, nothing was tight at all but neither was it loose. Then, I wear it to work. I even took a picture before heading off to work, where everything was still perfectly out together and no issues were visible. And then I sit down at work to eat my breakfast, and notice that stitching RIGHT OVER MY CROTCH had come loose and made a hole. Not popped, the stitching was not broken or anything, but just unraveled. Nothing was tight, and sitting down and walking felt normal so I know I didn’t strain the fabric at all. The stitches were just loose, and the thread was all over the place. Luckily I don’t think anyone saw, I was able to keep my legs crossed or cover the problem area strategically with my water jug or bag. But my house is an hour’s drive away from my work, so I couldn’t just go back and change. I had to borrow a stapler and STAPLE THE HOLE SHUT. Yes, lesson learned, I bought several emergency sewing kits that I will stuff in everything I carry with me everywhere in case something like this happens again, but still. It was BRAND NEW. Not only that, but as I was in the restroom stapling my new suit pants back together, I found the issue. The crotch area was just basted together, no backstitch or proper finishing at all. And it continues down the leg, I had to be careful not to bend my legs too much or those seams would also unravel. They already loosened a little bit and risked showing my skin underneath just by walking. I managed to play it off and keep my body posed in such a way that it was unnoticeable, especially with help of the staples, but still! Super embarrassing, especially since I’m in a large training class right now and everyone found out just because I had to ask everyone if they had a sewing kit on them. I was so ready to chock this up as a win, too. Good thing I postponed my review. Sloppy sewing all around really, once I took a moment after getting home to look closer. Some areas are sewn well and finished properly, but others are still only basted shut or the end of the thread wasn’t anchored at all. I’m going to spend a lot of time re-doing the stitches, because I’m too stubborn to send the piece back and I know how to sew better than whatever machine made this anyway so I don’t wanna waste the fabric. Such a disappointment.
