If you start with a basic pattern that fits well it is possible to draft exactly what you want, but it is a skill. I'm not sure that software would do the job well. I've never used any myself, but have heard negative comments from acquaintances who have tried. If you can find several patterns that together make what you want, you might do better with that. They don't need to be wedding patterns -- look at regular dresses and tops as well. It will probably be easier to work with one pattern company, since they would be using the same basic template for their patterns. Make a muslin to check for fit, and to make sure the pieces go together properly before you cut your good fabric. JoAnn's puts their patterns on sale from time to time at a reduced price. That would be a good time to buy 5 or 6 patterns that together do what you want. Good luck!

When you sew the loop side on, take a piece of fabric doubled to the size you want and sew it on with the loop tape. That will be on the inside and provide a tab. You can read articles about this by googling it. Here is one. Here is a link that might be useful: Bridal dress sewing

I have a huge to-do list but haven't gotten to all I want to create. I'd sew everything I wear if I had the time! I'm only in my mid-30's but also hate most everthing out there. I;m a snob when it comes to fit, and can't stand to spend money on all the pants that have droopy seats, too-big legs, etc. As far as good patterns, I find McCall's fits the truest.

Get a pattern alteration book to help you with simple basic alts that will make a huge difference. Once you have acheived that, those 3-4 basic pattern pieces will becomw the patterns you use for everything Shorts, pants, LS and SS shirts, vests, etc. Most garments are constructe from the same patterns over and over again, with the style changes coming from fabrics, necklines, closures and opening, etc. Because once you find the shape that looks good on you, you will want to recreate it again & again. Why fuss around with a bucket if patterns? And I find it to be fun to create my own look this way. And I have learned so much! If you are really at a loss, do what I did after my body 'settled' after having children - go to some really high end stores and try on what you like (don't even look at price) If you like the fit, take notes in the dressing room & search for patterns that duplicate the look. That's much better than sewing an outfit up from scratch and then finding out you look like a damned petunia in a flower pot. (Yes,I did that. Wasted over 12 hours on one dress!) Good luck!
