Has anyone seen a tutorial here for adding a crotch to a little sundress? Or can anyone offer some advice?  Basically I have a lot of cheap sundresses I've accumulated and I want to convert a couple to rompers, for bike riding etc. 
I don't want to start cutting without knowing what I'm doing so can anyone offer some ideas on how to turn the skirt bottom to bloomers?  Should I maybe put elastic around the legs?  Do I need to cut the bottom in a specific way?  I don't know where to start. 

I'd like to say that I've searched these boards and didn't find anything that worked.  So please no sarcastic replies about using the search button.  Thanks. 

Also I have some rudimentary sewing ability- so when I say quick n dirty I know recons aren't easy but the more steps there are the more likely I'll mess up. 

I guess I should start posting some of my recons!

Hi craftsters!  I have posted very little because I have little to offer, being so inexperienced.  I've only made a few pairs of t-shirt panties and I won't be posting those here!  Lol

I'm working on the free vintage swim pattern I have seen recommended here a few times:

The instructions are not as bad as everyone seems to complain but the pattern is missing a lot!  In fact, when I read the blog of a girl who struggled with i (very helpful by the way) she has pattern pieces I don't even see on my printout!  I'm missing a whole piece of the body, not like a crotch or strap where I can wing it. 

On the off chance that it's a corrupted file I'm trying to download, does anyone have a copy of this pattern on their hard drive they could e-mail me?  Has anyone had any experience making this? 

TIA for your help, and I promise, as my projects get going, I'll post them here!
