My three year old has just about outgrown her favorite "rainbow dress", a cotton striped dress purchased from Target maybe 18 months ago. I did find the exact dress on Poshmark, but the listing was removed a few days ago (drat!)

I'm trying to find her a replacement for back to school. The closest thing I've found so far is a Hanna Andersson dress (http://www.hannaandersson.com/pdp.aspx?from=SC&pcid=1590&styleid=48277&simg=48277_62S), but if I'm going to spend the money, I'd prefer to buy a size 100 (rather than 90, which IS available, but she may outgrow by mid-year), and it's sold out in that size.

Anyone seen something that could be considered a "rainbow dress" - striped, cotton, and available in size 3/4? I'd love for it not to be very expensive, since I thought I was already done back to school shopping - ideally under $30 including shipping, and that's if she reallllllly loves it Thanks!

Here's the original dress:
