This piece really will become your favourite Tank, and definitely a main staple in your wardrobe! It's amazing worn as a top alone, or as an underpiece under any sweaters, tunics, short sleeve or long sleeve tops. There are 2 options for this... one with side rushing, and the other with just a stright side seam, and both styles just hug & hold your figure in beautifully. 
The side rusched ones are longer, which is ideal if you're wearing  leggings and feel like you'd like a bit of coverage in the crotch and bum area
 (if you are tiny like these particular models you can also wear these as a mini dress lol)
