Cute Little Suit
This is how I styled this cute little suit. I added the red bow tie and red vest from another company to add more color to this, and paired it with these Jordan’s. I will say the material is a good quality but not too heavy where a kid would get hot wearing it. This is a size 2T, which was bought for an almost 3yo that is on the smaller side. I would size down.

Great suit for kids
Great suit my son wore it to a family members wedding he looked adorable. We talked with other parents and some spent hundreds on a suit and they thought ours was even more expensive thejaws that dropped when I told them what we paid and where it came from…

Stained upon arrival
This suit came stained on the front and if I didn’t NEED it, I would have absolutely returned it. I took it to the cleaners already, so I don’t have a photo. I do like that it came with different tie options (bow tie or regular).
