Her official site still has them. Anon are you buying some??
I know I previously answered this but I never tagged it properly. Anon I know he has worn RUN5 facemasks. This site carries some but the designs xing has worn are not listed or might already be sold out.
Generally not very often, but if is something sold out from their current seasonal collection I have seen it become available again. Another exception could be outerwear/jackets that become unavailable in the sp/sum but return in the winter.
ooh thanks for the tip!
