In tags with more than one and or or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.

{% if true or false Casual Dress 21 Forever Boutique winter and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andDress Forever 21 winter Casual Boutique false and false or true %}
  This evaluates to false, since the tags are checked like this:

  true and (false and (false or true))
  true and (false and true)
  true and false
  false
{% endif %}
