Difficulty: Moderately Easy
Step1
Go to a reputable store, such as a place that specializes in lingerie or a department store. Both places will have fitters who can measure you to make sure you get the right size. Don't worry, you can keep your shirt on.
Step2
Be open to trying a few different styles on as well as more than one brand. Just because you're a 34C doesn't mean every 34C will fit.
Step3
Know what you want before you start shopping. If you are small on top, you can get away with a stretchy tank. If you want more oomph, look for padded bras that give you some shape.
Step4
If you're active, invest in a good sports bra.
Step5
Bring along a fitted white t-shirt. Try it on over the bras you like so you'll be able to see all the lumps, bumps and seams before buying.
