I know lemonbrat is good. I have one, and many people enjoy them, good visibility and such for my wear, but I have had my suit for less than a year.

I dunno!

GentleFur's is an amazing suit making group

depending on your timeline

they do lots of visually amazing work, but never afforded them so cannot speak to how their work wears.

There are so many talented makers out there that this question tends to be a little on the vague side.

Perhaps your friend has a particular style they're looking for; eg, realistic, semi-realistic, toony, kemono.

Once you have that, you have can focus upon that particular style of maker and see who is good in that particular field.

GlitzyFox is what I would suggest, or else Fin & Fursuits
