Granted, rigged mesh made for the system body doesn't always easily fit Ruth2 or Roth2. This holds true for Linda Kellie's line of mesh products as well.

It doesn't help male avatars that she has only ever made three pieces of men's mesh clothing of which at least Roth2 v2 can only wear the jeans. I recommend you to pick them up anyway. You never know when you'll need them, and, in particular, the alpha mask is very useful.

Ruth2 avatars can only use fewer than half of the clothes offered at Clutterfly, too, especially Ruth2 v4 with her very pronounced shoulder blades. But Linda has made so many women's clothes that there's still a lot to find that you'll likely be able to wear.

The long straight skirt, the straight miniskirt and the circle skirt are too wide around the waist, but they work amazingly well with Damien Fate mesh tops. The Clam Diggers are Fate-compatible, too, but if you have a Ruth2 v4, you may want to make your own alpha masks for them because those added by Linda are a bit too extreme and alpha out way too much.

As for dresses, the babydoll dress, the halter dress/Lil Tennis Dress and the strapless mini dress/Glitter Dress are likely to work without any alpha masks. The ruffled bottom dress/Afternoon Party Dress works, too, but it may need custom alpha masks again.

Clutterfly isn't 100% mesh. There are also layer bikinis which could be useful for Ruth2 v4s who don't have enough beachwear yet.

Also, don't forget to pick up the jewellery.

Last but not least, there are also "raw" versions of the pre-textured clothes and of even more clothes in another building. If you want to re-texture Clutterfly clothes, these are way more convenient than the pre-textured ones.

Some of the shopping destinations to follow, by the way, will offer retextured Clutterfly clothing so you'll get even more of it.
