The top is definately not the best fit for my SLink body and the only way it looks like a good fit is because of this pose. As for the matching panties, no pose could cover up the fact that they weren’t for SLink.
If I remember correctly you get a Maitreya, Belleza Freya and Legacy fit. You also get a 10 colour hud for both the top and panties. This hud also allows you to change the colour of the frill as well as I think the lacing.
I now wish I’d picked one of the stronger colours to show it off better but as it’s a freebie it costs you nothing to grab this gift and try them out for yourself.
