It's american apparel and they are men's sizes if that helps any. 

I don't know how their walk man shirt is but I bought the black shirt in a medium and it fits fine.

I wear large in women's american apparel.  

I bought this shirt and I got a large - the XL one was pretty big - and I'm not small!  It fits similar to the Georgia shirt (which I also have in a L) but this one is a little looser.  It is not preshrunk, however, so it will probably shrink a little. 

lol, of course.  That sucks.  I shrunk a sweater once...I gave it to my friend so her baby daughter could wear it.

I was wondering the same things about the shirt. I'm going to order one soon, since I didn't get a chance to buy one at the concert on Saturday, and I don't want it too big or too small. I also have a, uh, "generously sized" bustline... Lol.

I'm also going to have my mom embroidery the dates from last years and this years Walk in Louisville somewhere on the shirt. She has a small sewing business and has a nice embroidery machine that will do it in like 2-3 minutes.
Does anyone have any suggestions on what would be a good place to put that? I know all the words/numbers are on the front, so I thought maybe somewhere on the back, but I don't know what would be a good place. I want it to be visible, and have room to add future dates as well. I also don't know how I should do the dates. I can either do "October 12, 2007" and "October 4, 2008" or I could just do "10-12-07" and "10-04-08"

Or would having the dates on there using a thin embroidery stitch look strange?  

haha, do that and tell me the results. LOL

I would probably get a small. The medium looked pretty big but they didn't have any smalls left at the Louisville show so I'm hoping they've restocked them by now.

Define big bust.  I've got D's, and the large makes me look like a boy, so I'm going to re-order a medium.

The embroidery stitch could possibly look cool...depending on how it was done.  The words and numbers are like paint-ish looking, so.  It's possible it could look a little wierd, but if the embroidery thread had a bit of a sheen to it, that would work.  I don't know if you can get "sheen-y" embroidery thread, lol.

I've been no help here.  Um.  You'd definitely have to physically have the shirt for yourself to decide what you think would look okay.  And I do think it's possible to add the dates, somehow even if not by embroidering them on, and have it look awesome.  It's a really cool idea, actually.  :)

I know it looks like paint, sort of, but I'm not sure how put the dates on the shirt and make it look the same. I've tired thinking of alternatives to embroidery, but nothing really comes to mind.

I also thought about having her start from scratch with a plain white shirt, and put the walking man on the upper part of the center on the front, but I don't know if that image is copyrighted. She can scan things into the computer, and transfer them to the embroidery machine, so it would be easy to put the walking man image on there, then put the dates on the back.
