Perfect fit and great quality for a costume
Color: Purple, Size: 34, Color: Purple, Size: 34
These worked perfectly for my husband’s Mayor Humdinger costume. The fit was spot on, the length was just right, and the color matched the picture almost exactly. The fabric doesn’t have any stretch, but it felt nice and well-made, giving the costume a polished look. Overall, a great choice if you need something that fits true to size and looks high quality for a costume.

Great dress/casual pants, but not all colors have the expanding waist.
Color: Green, Size: 31
I ordered the red pair in March for a Lady Gaga concert. I loved the material and they were comfortable and cool in the arena with all the people. In addition, with my 2026 New Year's resolution, I have been running everyday so I have dropped 2 pant sizes and most of my pants now slide off my waist. I really liked these pants because they have an expanding waist (like the newer tuxedo pants style), so even if I fluctuate in size they will still fit well. With summer approaching, I decided that I would replace my old pants that are now too big with these, so I ordered the other 19 colors. Sadly when they arrived, not all the colors come with an expanding waist. The colors that have the expanding waist - Red, Aqua, Light pink, Green, Hot pink, Royal blue, Purple, Navy, and Black. With my waist size still changing, I am hesitant to keep the other colors since they have a very tailored look and if they are slightly too tight or too loose, they will not look as clean. I am returning the other colors since my waist is still changing...I guess 9 out of 20 colors isn't bad.

For its array of loud colors and audaciousness to capture the slim physique fashionably
Color: Hotpink, Size: 34, Color: Hotpink, Size: 34
Let me say that I love that the MOGU brand. It’s right up there with the International Concept which has been discontinued in Macy’s except for the women’s apparel. 5 out of 5 for the look, the feel, and the affordability. Its now one of my go to brands
