V-neck, turtle-neck and crew-neck can be unisex. Even Boat-neck (also called a bateau neck) for a brief time had unisex privilege. However, a low-cut square neck screams, "Feminine". I love it. Several of my bras provide excellent cleavage and plays quite well with square neck tops. Like you don't look when the opportunity arises?
This was an impulse buy from the web site Venus. Its clothing tend to be youngish and sexy so I am always cautious. For the above sweater, I will grant you sexy, however, it really looks good with jeans and especially stands out with white slim jeans and heels.
Also, I love the way the sleeves are made. When pushed up the provide a balloon sleeve full look.
Balloon sleeves are long, puffed sleeves that are gathered at the shoulder and then puffed out and gather back at the wrist. Sometimes, the sleeve puffs out lower than the shoulder, but it is still a full puff rather than a tapered flare. (Sleeves in Fashion)
A feminine differential, keeper.
