Good quality, quick delivery

I ordered two pairs of the organic cotton leggings and a skater dress for my daughter. The ordering process on the website was straightforward and I received an email confirmation right away. The package arrived in just 4 days, which was faster than I expected. The clothes felt soft and well-made, definitely GOTS-certified as advertised. My daughter wore the leggings to school, and they held up well through a day of play. I had a quick question about washing instructions, and customer service responded to my email within a few hours. Overall, a solid experience from start to finish.

Reliable choice for basics

I've bought from Mightly a few times now, mainly their organic cotton basics. This time I got some boys boxer briefs and a zip-up hoodie. The quality is consistently good across all my orders; the fabric holds up well to washing and active kids. My previous orders for girls briefs and camisoles also lasted longer than other brands. Shipping always takes about 5-7 days to reach me, which is fine. It's nice to have a reliable place for everyday wear that I know will last.

Good value on sale

I was looking for some durable clothes for my son and found Mightly during their End of Season Sale. I picked up a few long sleeve tees and a pair of joggers. The 20% off sale made it worth trying them out. Shipping was free because my order was over $50, which was a nice bonus. The quality seems good, especially for the price I paid. I usually shop around for deals, and this felt like a smart purchase. I'll keep an eye out for future sales.

Comfy shorts, took a bit to arrive

I ordered some bike shorts for my daughter. They're comfy and seem pretty tough, which is good. Took about 6 days to get here, which felt a little long. But they fit well and she likes them. Overall, it was a decent experience.

Love these graphic tees!

I just received my order of graphic tees and they are awesome! The designs are so cute and the cotton is super soft. My son loved them immediately. The colors were vibrant, even after washing. I'm so glad I found this brand! I'll definitely be back for more activewear soon!

Anyone know if Mightly ships fast to California? Need some joggers for my kid before a trip next week.

C Cody 2 months ago
Mine usually arrives within a week, maybe 5 business days to SoCal. You should be good for a trip next week, I think.

I'm in NorCal and it's typically been pretty quick, like 3-5 days for me. They use standard shipping, afaik.

Hey, wondering about Mightly sizing. Are their clothes pretty true to size or should I size up for my toddler who's always in between?

R Rachel 3 months ago
I've found them pretty true to size, especially the leggings. My kid is average build and their usual size fits well with a little room to grow.

For my littlest, I always size up if they're on the cusp, just to be safe. They hold up great though so even if it's a bit big, they'll grow into it.
