If you like the pool... go.
I don't... so I don't go.
For me it's not an issue of how I look in a bathing suit because my current bathing suit... I would wear it as a normal shirt if I could.

I love it. I love the way it makes me look. I just... I don't like swimming all that much... or the sun... blech. So... I don't go to the pool.
But... not because I would feel bad about going. I can understand the desire to not buy a new swimsuit. So don't. But... go to the pool. Nobody is going to care. You're not THAT overweight. If you need to, wear board shorts with a tankini type top, or even a one-piece. I've seen it a TON lately. It's the fashion, and nobody is going to judge you for wearing it. I certainly don't.
