Triathlon Apparel Question

I have a duathlon coming up in May and my club gear won't be here in time. I figured having two tri outfits wasn't a bad idea and bought this one:

Here it is on me (ignore my messy room...):

And if I don't yank on the top every 5 seconds, this happens:

I'm trying to figure out if I need to return the top for the next size bigger. I know it has to be tight if you're going to swim in it, but I'm not sure where the line is for too tight?

I ordered an XXS in our club gear from Louis Garneau and this is an XS from Sugoi.

It's fashionable to show your tummy!:D

If you go up a size on the top for length, will it still be snug enough?

hmm. I'm gonna guess that the next size up won't make THAT much of a difference. Maybe 2-3 sizes up, but I doubt the next size up would be all that difference. And you do want them tight, sooo... I would just flaunt the tummy! We work hard for those abs you know! :D Well, I don't! I NEED to, but I dont... sigh..

The fit doesn't look bad, honestly, the top just looks short. You could try one size up, but it might feel too big. Maybe your torso is just too long for that style. :(
