My 3 year old is fairly short and thin. 3T clothes are often loose on him. I got 4T and they were snug but not tight. Could have gone one size bigger.
For reference he wears 4T underwear in other brands.
My son is on the Autism spectrum and potty training has been difficult. Finding the right underwear has been a task. We spent a good amount of money buying underwear for him that he would just not wear. I saw the reviews for City Threads Briefs and a lot of moms said they were very soft and sensory-friendly, so I decided to buy ONE 3-pack to try out. Of COURSE my son absolutely loves them! They're super super super soft, and such great quality! Once we knew he would actually wear them, I purchased 3 more 3-packs. They are definitely a bit pricey, but they WILL hold up. I typically wash all of my clothes in tepid water and always dry on low heat as to avoid shrinking. They have held up to numerous washings so far! I definitely recommend these briefs for children with sensory issues. There are no tags, and nothing that will "dig in" to sensitive skin.
Good quality made in us
My som is generally a size 12 still wearing 10-12’s
Bought a 14 and while waist is fine its tight fit around the legs
14 fits like a 12
They run on the small side so order size larger than what you plan
My kid loves the softness of this underwear and the lack of tags. I like the quality of the fabric - they last until he grows out of them and the hidden seams. We’re on our 3rd size now.
Good quality material
