Just a quickie post because I noticed Dav rainboots were on clearance on Hautelook. Whenever readers email me about rainboots for petites, I recommend Dav because they come in a mid-calf length, plus they have a heel! I bought the solid black pair in the shorter length after doing lots of research (unfortunately not included in the sale). The stubby heel takes a little getting used to, but now I always reach for these over my Burberry flat ones.
The Hautelook prices are actually really good (I paid $50 for my short ones at DSW, for reference) and shipping is $7.95. I own sz 34-35 and it fits just like a US 6. Click here if you need an invite (commissioned if you make a purchase).
