What our customers say
- SShannonRated 1 out of 5 stars2 weeks ago1 Star
I am suuuper disappointed in the sizing of these. I ordered an XL thinking they’d be so loose and comfy. I am 5’10 and 140 lbs so it is rare that I need a L, let alone an XL. There is no way the XL we ordered for my husband will fit. Even my small 10 year old is feeling tight in his size 12 set and my petit 8 yr old is snug in her size 10 set. Overall, we are so sad because we were so excited for this cute matching set from a Canadian company. We bought above our sizes so we could wear them for years to come. They feel like great quality and we certainly paid enough to get something that would have lasted…I am not even sure we can wear them :( I hope customer service can help us out.
Care
Life’s messy — laundry shouldn’t be. Machine wash cold with like colors, skip the harsh bleach, and tumble dry low. Remove while warm for that just-right softness, and iron if needed.
