Flexi Skirts - Attaching Panels Question

So of course I'm new at making skirts, and ive been closely following an awesome tutorial by Natalia Zelmanov. Ive gotten everything down except the panels actually attaching. When My avatar moves, the panels get all spaced out and if shes not wearing anything underneath, ut oh! (but of course she is).

I have a picture of exactly what I'm seeing at the link below.

Can anyone tell me what I do to fix that? Am I missing a step?
And does anyone know any tips to fitting the skirt a little better?
As you can see, a little but of her underskirt is showing

Thank you very much.

Try playing with the flexi options in the feature tab. Softness, gravity, drag and so on will change how the panels react to wind or your avatar walking. For a less bouncy skirt, increase gravity.

Also, try rotating the entire skirt forward at the waist to cover the butt better.

It's really not easy and it's never perfect.

Once prims are attached to an avatar they become phantom which means that as the skirt panels swing around when the avatar moves, or the wind blows, they will go right through the avatar so the avatars legs, hips, etc will show through.

One trick is to make the texture under the skirt match the skirt as much as possible to make it less noticeable. Busy patterns or dark colors make the whole thing less noticeable.

Also as far as panel spacing. From all the skirts i've seen they layer the panels/add more panels to prevent gaps when you move.

It takes a lot of practice to fit a skirt so it looks right. In fact, I think that fitting is actually the hardest part of making a good skirt.

Veldin is right.... a skirt with fewer than about 12 panels doesn't have enough overlap to cover the open spaces between them. I usually use at least 18, and overlap them so that each one covers about 1/2 of the next. Work with the taper on individual panels too. Overlap isn't as important at the waist as it is at the hem, and you don't want the panels bunching up too much at the waist either, so get them narrow at the top.

As Sylvia says, it also helps to rotate a skirt forward at the waist. That makes it lie flatter across the tummy and not so tight across the backside.

Another thing you may want to try is building a skirt with two layers. Make the outer skirt a bit fuller/poofier than the underskirt. When I've done this, I have made the outer skirt slightly transparent, so it's shimmery. It makes a nice effect, especially in an evening gown. You can either link the two layers as wear them as a single skirt or wear them separately, as two different attachment points (hip and stomach, for example).

There was another question about fitting flexi skirts this week. Specifically, it was about covering the backside properly. It's late tonight, so I won't repeat the comments I made there, but take a look at them and at some of the other suggestions in that thread.

Good luck. You're going to have fun.
