### ⭐⭐⭐⭐⭐ 







  
  
    Good Quality & Comfort
  

*by S***. on Reviewed in the United States on July 28, 2017*

My four-year-old grandson wore this to my son's wedding, and it fit well, except my grandson needed a belt. It was lightweight enough that he was comfortable despite wearing it to a July Arizona wedding. It arrived on time, washed well, and we are very pleased with the outcome.

    Very nice
  

*by M***A on Reviewed in the United States on May 15, 2018*

We bought this for my son to wear to a Mother& Son dance, he looked so handsome. He’s 9yrs but he’s pretty husky, so we always have to order his size way up. Got him a 14, everything fit him perfectly, the pants were longer than expected, I just folded it in. I haven’t ironed it yet, only steam cleaning and still looks brand new. Held up well at the dance, his 9yr old butt was dancing all night long😂

### ⭐⭐⭐ 







  
  
    Sizing not proportional and inconsistent
  

*by L***U on Reviewed in the United States on September 29, 2019*

We ordered four of these suits for our boys for a wedding. Each kid got to pick his own color and they were so very excited about it. The suits arrived, we put them on, and each kid was absolutely swimming in their suit. The pants didn’t stay up for any of them. We shifted all the suits down the line (we put the 3 year old’s suit on the 5 year old; the 5 year old’s suit on the 7 year old, etc.) and they fit better but overall sizing was still off. While the shifted suits fit in length of pants, the pants were still too big in girth, and while the shirts of the shifted suits fit in sleeve length, the tails of the shirt were too short to really tuck into the pants, and the neck of the shirt was too tight. Even so, we were in a pinch so returned the huge sizes and reordered all four suits down two sizes from what they should have been. Sadly this meant the boys no longer got to choose their colors because each size needed (2 sizes down from their regular sizes) was unavailable in their chosen color. In the end they decided to all wear the same color and we made the new sizes work with safety pins in the pants, leaving the top neck button unbuttoned, and constantly re-tucking shirts most of the night. For each size we were baffled as to why the neck was so tiny, the waist was so enormous, and the torso was so short. That being said, we still got so many comments on how adorable our four identically-dressed boys were in their fancy suits, and the boys loved getting dressed up for the first time ever. They said the suits were comfortable except for the pants being scratchy and irritating when the shirt would come untucked and the pants were directly against their skin. In the future I’d only have them wear these for short events rather than an all-afternoon-and-into-the-night event. The returns were easy and the new suits arrived just in time for the wedding. They washed well and held up through two permanent press cycles so far. We ended up ordering sizes 9mo, 24mo, 3T, and 5 for a 7mo old, 3 year old, 5 year old, and 7 year old, respectively.
