I love wearing tank tops all year round, and wearing blazers, or cardigan's over them. Here is a cardigan from Mango that caught my eye recently, and another from Forever21 and one from TopShop, all would look cute on petite girls. ~Isobella
Mango, CARDIGAN PIETRO, $59.90, XS-L
This Knit Sweater Cardigan from Forever21,$29.80, looks super warm!
This blazer is from TopShop, a size 6, a bit big, but I like the equestrian look but when you are petite it can be tough to find a fitted blazer, but they are out there.
