I am looking for a adult (Large) Blues Clues Steve shirt.  It is a
green striped shirt.

Hi and thanks for your question,

You can purchase 'Steve's' green striped rugby shirt online from
ColumbiaKnit Factory Store ( http://www.columbiaknit.com ), it is
available in Large or Xtra-Large sizes for $36.00.

The link to the factory store is
http://www.columbiaknit.com/factorystore.html
and you need to choose the 'Clues Adults & Kids' link further down the
page which will open a pop-up window where you can place your order.
(an alternative link to the product is
http://www.columbiaknit.com/rugbymens.htm )

ColumbiaKnit is the recommended place to buy the shirt on one of
Steve's fan sites: http://members.aol.com/periwinklekittee/steve/steve.htm
- which also tells you how to make them - should you be feeling
creative!).

The only other place I found was on ebay (type 'blue's clues steve' in
the search box at http://www.ebay.com ).  There are a few shirts on
there, but I think the sizes are too small (forgive me I'm not used to
USA sizes), however it may be worth a look for good prices.

Search Strategy:
I searched on Google with the following terms:
Blues Clues merchandise Steve shirt
://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=Blues+Clues+merchandise+Steve+shirt

"Steve's shirt" nickelodeon
://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=%22Steve%27s+shirt%22+nickelodeon&spell=1

I hope this helps and you get your shirt,

Kind regards,
Ali

Great job, I have ordered the shirt.  My daughter will be thrilled her
daddy will be Steve for Halloween.  Thanks again!
