When it comes to tank tops, I'm a cheapy. I figure even the priciest tank top can only last but so long...
For "wifebeaters" in the States -
- Target has some nice ones in their active department by Prospirit. $7.99. $5 bucks a pop if you get them during a sale.
- Old Navy has good ones in several different cuts. I get the "perfect fit" cut b/c it's a bit longer than the others. I think their generally around $10.
- I haven't tried JCrew's tissue tank, but I am a fan of their "Favorite" tank which run about $12.99 I believe. They're a bit thinner than the Old Navy/Target tanks.
- And finally, I agree with Luna. Express always has good staples & would be a good option for an embellished tank.
Additionally, I haven't owned them myself, but I hear good things about C&C California T's and tanks. There just a bit pricier. Good luck
