I would say to incorporate fall colors.  But moreso, pick something that flatters your skin tone and you!

Blue is an old-school wedding tradition, if that appeals to you.  A pink could work well with grey, although it's not a fall color per se.  If you want something that works with the season, maybe a garnet red, or a deep purple?  I'd say, prioritize what looks good with your skin color over what will match the season, and take it from there. 

(For reference: I'm wearing bright blue for our party after wearing my mom's ivory dress for the actual ceremony.  I don't look that great in white or ivory, so I chose the dress that I bought based on what looked good with my coloring).

One more thing: the only downside of bridesmaids dresses is that they won't have very big swatches of most of the colors, so if the sample dress isn't in the color you're considering, it can be hard to tell how well a dress in that color will look on you.  For that reason, it might also be worth hitting up a department store or two just to check out what a whole dress in that shade looks like.

And I second the idea of a grey dress - probably not matching perfectly, but going a couple of shades either darker or lighter could work really well.  Only if it suits your coloring, though.

I always think of earth tones and reds/oranges for fall.  But if you haven't picked any wedding colors yet, pick something that flatters your skintone.  The season doesn't matter and I almost picked a color I had no interest in just because of the season.
