This Old Navy Marled V-Neck Sweater that I picked up earlier this year is now on sale for only $7, but sizes are very limited. You can also check out this similar version on major sale! I am also loving this longer tunic version - save an extra 30% with promo code SUPER.
Here are the rest of my outfit details:
Old Navy Vest - old, similar here - only $25 (reg $68)
Jolt Jeans - old, similar here - I REALLY like the brand for the price (only $30, reg $54)! Be sure to check the size chart, I usually wear a size 2 or 4 and I am a size 7 in this brand.
