Special thanks to Sunflowerchilde for her AWESOME advice. Sarah and I say "YES YES YES!!! Whatever advice you have, we want!!!" :)
So, we went to REI and I bought my suit. I tried on the one I liked online but didnt love it in person. It didnt really flow well for the curvy girl with tatas. But I loved the one I did buy. (Yes, I DID buy a suit!!!) I went with a two piece, made by Skirt Sports.
I really like it. It was very comfortable. Thanks to the aforementioned commenter, we are going with our initial thought of not wearing shoes, since the lake we'll be in is fine for swimming.
I can't believe it! I took the plunge and bought a tri suit!!!
And a pretty awesome book...
