Concept:
- English usually names a type of shop using a noun+noun compound, not an 'of' phrase.
- The first noun works like an adjective telling us what the shop sells, for example 'book store', 'grocery store', 'clothing store'.
- Phrases like 'a store of clothes' are technically understandable but not how a fluent speaker phrases it.
Step 1: Identify the problem with the underlined phrase.
'a store of clothes' tries to describe the shop using an 'of' construction, which sounds unnatural in English.
Step 2: Recall the correct naming pattern.
For naming a shop by what it sells, English uses a compound: item plus store, so 'clothing' plus 'store' gives 'a clothing store'.
Step 3: Test each option in the sentence 'I went to ___ yesterday.'
'stores of clothing' is plural and still uses the awkward 'of' pattern.
'stores cloth' and 'cloths of stores' are grammatically broken and meaningless here.
Only 'a clothing store' fits smoothly as a singular, natural noun phrase.
Final Answer: a clothing store
