If we were you, we would add the Me Too Heather Grey Backless Sweater Top to our cart ASAP! Soft and lightweight stretch knit sweeps across a wide neckline, into long sleeves (with fitted cuffs), and low V-back.
Kimchi Blue Sunny Surplice Sweater - I bought this sweater April I love it. I wear it with a lacy bralette underneath. The V neck is not too deep, but just deep/wide enough to let the bralette peek through.
