Ursa M is a delightful clothing set with a choice of a conforming or dynamic top, and a cute and rather daring little dynamic skirt. It has a number of morphs included to help with the fit, and an option to cut away the front panel of the skirt to show off lacy panties or longer leggings. A superb set for all your Steampunk themed renders, it is also just a cute casual set--the top can be paired with jeans or skirts from other sets, and the skirt looks adorable with tank and crop tops.
The skirt does well almost all the time with just the "Sim from memorized pose" and even auto-follows pretty well in standing poses.

Thanks for checking this out! The model is Gabriella by Heatherlly at the RMP, there is a link in the Vendor Credits.
Earring is by Sveva, originally for V4, Boots are from Rhiannon's Dark Alice set
