Question about clothing size from Rylee and Cru

This may not be the exact place for this but I saw another post on here from a few years ago mentioning Rylee + Cru to do matching “mommy and me” outfits. I’m assuming there are some moms on here that have purchased from that site! Can anyone give guidance on the sizing for the women’s dresses? are they TTS? I would love to try their clothes as they have cotton options and matching options, but I can hardly find ANY reviews for the women’s pieces! I’m specifically looking at the Jess dress currently, and have had my eye on the Jane dress in the past.

Thanks! sorry if this isn’t the place for this, if there is a better place to post this please let me know.
