Teen denim skirt

My granddaughter loves her new skirt. She tried the size 12 & 14 for fit and the 14 worked better for her. I would suggest sizing up. Very cute look and the larger size gave her needed length!

Beautiful!

My 8.5 year old daughter is OBSESSED w high low dresses - ideally we would have bought a Medium, but they were out of stock, so we went with a small and it fits fine - it sadly prob wont fit her after summer but we just had to have it, so small it was! Fabric is so sweet!

My daughter is 8.5 and we ordered the M (10). Its so sweet - I did not purchase the skirt to match but so far she has worn it with wide leg sweat pants and a high waisted skirt from zara. She loves it!

High Quality Dress

My daughter chose this dress in blue for her school dance. Vibrant color, high quality dress. The company was also very helpful in dealing with returns and exchanges in order for us to get the best size.

Returned dress

I’m extremely sad that I sent this dress back the next day as it didn’t fit my granddaughter why would I lose $20 for sending it back immediately with the tags on?

Sisters pink shorts

You should have my 11 yr old sister be a model for you. Our mom and dad get her clothes from here and she looks better than the other models. She has brown hair and sexy eyes and a really fine body . All her shorts and bikinis look awesome. Im a few years older than her and my friends all drool...

Extra large is tiny

Great style, but definitely see through white and the extra large was maybe more like a size medium 8-10
