Awesome value! Great fit!
Size: XX-Large, Color: Black
Complete men's suit for under $70!!! Crazy!! My husband is thrilled with this suit! We ordered a XXXL but it was a bit baggy. Ordered the double XL and it was perfect! Husband is 6'1, waist 38, broad chested. No adjustments or hemming needed! Love it!

I felt cute
Gorgeous. Little snug for the jacket for recommended size but I got 6 months to lose some stomach to fit better LOL I don't blame the jacket.

Color is not accurate
Size: Medium, Color: Grey
Suit quality is good. This is NOT dark grey. Its a very standard grey when you have it in person. I might return just for this reason as we were really looking for a dark grey suit.

Stylish, Well-Made, and Comfortable!
Size: XX-Large, Color: Black
I recently purchased this 3-piece suit for my grandson, and I’m very impressed with the quality and fit. The fabric feels durable yet soft, and the tailoring gives it a sharp, modern look without feeling too stiff. The vest adds a classic touch and elevates the overall style. The sizing was accurate, and the suit was comfortable to wear for long hours at work and events. The jacket, pants, and vest all coordinate perfectly, and I appreciate the attention to detail, like the lining and buttons. Whether you’re attending a wedding, business meeting, or formal event, this suit looks expensive without breaking the bank. Highly recommend for anyone looking for a versatile, stylish 3-piece suit!

Sharp and Expensive Quality Tuxedo for special events!!
Size: Small, Color: Black
I researched for several tuxedos for my son's prom, we chose this one, and I'm very glad that we did! The fit is nice, the durability is great. Very classy looking! The quality is really surprising for this price, it looks like a $200 dollar suit. My son is very picky and was very pleased with this tuxedo. The seams are very good and all the buttons are correct. We did receive the tie and everything that was supposed to be with it as I know reviews were saying they didn't get certain things but we did. I really like the adjustable waste because my son is very slim, but tall and has a long torso. This Tuxedo allowed him to be super excited that we have everything we need for his first prom! True to color as we purchased the black and it is sharp!
