Hi Joyadee,

I wear size 14, mostly. I don't kow what your version of "big" is, but I wear larges and extra larges, for the most part, so I'm not small.

I tend to go for one piece tri suits. Comfortable to swim in, then just hop on the bike. No trying to pull on dry shorts over a wet bathing suit. Saves time too. With a one piece, I like the lack of waist elastic, and also like that it keeps my lower back covered from the sun.

That said, we do sell plenty of two piece outfits (both with bathing-suit-style bottoms, and with bike-short-style bottoms). More two piece than one piece, actually, so I may be in the minority. You may want to try on a few different types of suits, for comparison.

Hope that helps!

Susan
