WOW! this suit really true to its sizes description... I ordered in a different company before this, but I have to return it TWICE because of wrong size fittings... Finally, this beautifully tailored suit timely arrived before my son's wedding reception, and we are ready to celebrate!!! Thank you and might order some different colors in the future... I wonder if they can make the pants in higher waist and straight cut or wider for the legs in the future as an option... Just a thought since slim fit pants are slowly outdating...

Great quality product!

Color: Black, Size: Large

Great product and great fit. I ordered a Large and normally wear a 42 Regular. Jacket was perfect, as was the vest. Pants waist is flexible and fit fine but length needs to be shortened. Overall, I’m impressed with this product! Highly recommended!

Fashion on budget.

Color: Black, Size: Medium

Beautiful, solid material, the texture feels expensive. Only returning because I need 2 sizes down as my son is very slim. Ordering an XS right away.

I am a satisfied customer (My 4th pair)

Size: 14 Years, Color: Royal Blue

I ordered several suits from YND. I started with them when my son was a size 10 now he is a size 14. I bought different colors. They fit and look great on him All the colors are perfect. Great fabric. Very comfortable. Everything is always as described. The price is right. Always on time.

Stylish suit and good quality

The material and fitting is very good. I would recommend to size down if you want a perfect fitting suit or if you don't have time to alter. I purchased a 4T and 5T for a 5 year old with longer torso compared to legs. The 4T ended up as a perfect fit with no room to grow whereas for the 5T the pants ran a little long but other pieces were perfect.
