Pre-children, I was a Sporty and Perky 34B.
Post-3 breastfed children, I am a National Geographic 34B.
Containing my tah-tahs is not really an issue, as there is not really all that much to strap down.
A good, comfortable, and most importantly NON-ANNOYING running bra is important!
As I've shown you before, I own a plethora of sport bras, from UnderArmour to Champion to GapBody to Old Navy to Danskin:
That bra? I got it for $5.00!
You guys. It's, by far, the best sports bra I have ever owned. Soft material, criss-cross back, tighter in the upper chest and looser in the waist, and a perfect length. With a little zip pocket in the front for my iPod. I bought size M (10-12) and while the inner bra part is a little too big for my mosquito bites, the overall fit is excellent. And it does not, at all, ride up when I'm running. KEY. It's the only bra I've ever owned that I feel comfortable enough in to wear without a tee shirt over it!
website to find some more. It's on sale marked down from $40 to $29. In both black and white. And Lands' End ALWAYS has free shipping codes.
[I bought both.]
No, I am not receiving any sort of compensation from Lands' End for telling you this. I'm telling you because I care. About you. And your rack. You're welcome.
Feel free to discuss your fave sports bra in the comments. But I guarantee you that mine is better. That is, my bra is better. Certainly not my boobs. Because yours are fabulous.
