I just signed up for a subscription but apparently Paypal hasn't released the money yet because I still can't access subscriber-only options.
Which gave me this idea: I think that you should be able to TRY ON subscriber-only items in the wardrobe if you're not a subscriber, just not check out with them. After all, if you can see the item on your Glitchen, maybe you'll be more inclined to pay for a subscription.
