The tank looks amazing on you! I vote small too.

I agree with everyone else! Where's the tank from?

I'd say smaller, but the difference is really small, so maybe both - one breezy and one comfortably loose

no difference so go with what is comfy.

a most important question...where did you fet those amazing jeans and do you think a pear would do well with them?

I pick the smaller tank and love the outfit with the bfs and black jacket! Gorgeous!

I can't see a lot of difference, but given that you plan to alter it anyway due to the armhole gape, I'm going to go against the flow and get the bigger size. I think it gives you more options given that current fashion tends towards a loose fit. You can do a semi-tuck with a looser fit, that won't work as well with a tight fit.

It's a lovely tank, so as long as you buy one...!!

THANK YOU all for the great feedback! I guess I should've trusted my instincts; I was thinking the small was better, but seem to be having serious sizing issues this season.

Details on the jeans: They're relaxed straight leg jeans from the GAP, 100% cotton and no stretch (my wash isn't available any more, though), "1969 original fit selvage jeans", link to similar:

Angie, thanks! I love tanks, and I know I have a good shape for them... unfortunately we have very little hot weather to wear them *sniffle* Like you I have to be very stern with myself and not buy more than I can realistically wear at the start of the season!

BJ, I do think a pear would work these jeans! I have a proportionally ample seat heh, and sized up in these to get a really relaxed fit (they're already relaxed to begin with). Info about the jeans up above!

Annaj, no worries the smaller size is loose enough to semi-tuck
