annoyed
Size: 8, Color: Cotton Stretch - Colors May Vary
i purchased the boxer brief. they fit perfectly. they are fairly soft and seemingly comfortable. not too thin or too thick, good for breathability. my biggest issues are the stitching being poorly done, making me worry the longevity will be lacking and the label stating “do not use fabric softener”.
the reason i am annoyed though, is the images show pink and gray colors only, which is what i was hoping for, or at least colors only. i understand all multipacks are marked “colors may vary”, but for the love of god, stop putting white pairs in these packs. white, nudes/neutrals, and black should be sold separately in their own packs. i do not want ugly old timey white underwear. i wanted colors, any colors EXCEPT white! i would however, have LOVED an all black only pack!

Okay
Size: 7, Color: Cotton Stretch - Colors May Vary
They fit good. The middle does ride up when walking. They cover good and go about mid thigh.

The cutest backpack!
Size: One Size, Color: Lilac Ditsy Floral
I was worried maybe this backpack wouldn’t last us the school year. I was pleasantly surprised as we are nearing the end of the year. It’s the most adorable pink and purple bag! It is on the smaller side but we’ve still been able to fit a normal sized folder in it plus her extra clothes and snacks with some room still.

VERY NICE BUT TOO BIG
Size: One Size, Color: Lilac Ditsy Floral
Let me start by saying its a great product and looked to be made very well. I did have to return it though because it was far too big for my child. Other than size being 1 size fits all with no dimensions given and, yes, somewhat smaller than other backpacks (for adults) it seemed to be a decent backpack. Too bad we couldn't use it but if you have a older kid would would great for.
