What do the connective particles do here


In this sentence そして、大人と同じ模様の子どもの浴衣や、子どもが着やすい浴衣をたくさん売っています from
<http://www3.nhk.or.jp/news/easy/k10010984931000/k10010984931000.html> I have
issues interpreting this と in ...大人と同じ... I also have prblems with や in
...浴衣や...

In full, I roughly translate the sentence like this: "Furthermore, they sell
many yukatas of children and adults of identical figure and yukatas which
children can easily wear."

I feel uncertain because 大人 seems to connect to の浴衣 via と. I don't know if
that interpretation is correct. I also feel uncertain because や seems to
connect the two sentence elements ...浴衣 and ...浴衣, but this can only work if
my aforementioned interpretation of と is correct, so I'm not sure here either.
I'm also confused because in my interpretation they are basically talking two
times of yukata for children. This seems redundant and therefore I feel like
its wrong.

EDIT: Could it also be that と translates to "with" here? "Furthermore, they
sell many yukata of adults with yukata of children of identical patterns and
yukata which children can easily wear."

I struggle with this because of onaji. The classification of onaji on
<http://jisho.org/search/onaji> doesn't really help me feeling any more
certain about the function I assigned to it in my translation above.




Try reading the 大人 bit as [大人(の浴衣)と同じ模様の]子どもの浴衣, where I've added the abridged
element in parenthesis, and used square brackets to block off the entire
adjectival phrase that modifies the final 子どもの浴衣.

I think it might help if you think of と同じ as a set rather than look only at と.

The や is there two connects the two (examples of) different types of yukata
aimed at children that are being sold. Basically, there are yukata for
children with feature A, and other yukata for children with feature B.

Additional breakdown:

A: 大人(の浴衣) -> yukata for adults

B: 模様 -> pattern(s)

C: 子どもの浴衣 -> yukata for children

Therefore, yukata for children with the same patterns as the yukata for
adults.
