Hope this works for you....

Wearing shirt, t-shirt, jeans, underwear, shoes and, of course, the socks, stand in your bedroom and call for your sis. If she comes into your room, you must ask her if what you are wearing is okay to go out in. If she doesn't come into your room, remove one item of clothing and call again. You can choose which item to remove. If she comes into your room, ask her the question; if she doesn't, remove another item of clothing and call again.

You must only call once per item of clothing.

If she replies but doesn't come into your room, you can only ask her to come into your room.

You may be lucky - she may come in as soon as you call, or she may not come in at all; or she may come in when you are just wearing your socks.

Of course, you could do this dare the other way round - start wearing only the socks and add an item of clothing each time.

You can either choose which way round (clothed to unclothed or unclothed to clothed) depending on your knowledge of your sister ... or you can flip a coin (heads for clothed to unclothed; tails for unclothed to clothed).
