im not a big fan of t-shirts. don't get me wrong some people can rock them, but being a curvier and more busty girl than most i find the average t-shirt terribly unflattering. this is roughly the process i go through when altering a shirt.
1.find a a shirt with an appealing design/color
2. make the first basic cuts.
3. put on the shirt and make the rest of the cuts (this is the only time i actually wear the shirt while cutting), this is the step where i make decisions about things such as strap thickness, what time of neckline and how low cut to make it.
tank tops such as these may not create a very polished look but they are comfortable, affordable, and unique.
