Have to wear a yukata with 〜なくちゃ
Grammar Explanation: Must do with 〜なければならない

Lulu has plans to visit a local festival with her friends from class. Her mother helps her dress for the occasion.
- ママ:
- 「せっかくお祭りに行
( くんだから」- “Since you're going to the festival and all...”
- 「やっぱり浴衣
( くらい着( なくちゃね」- “You really should wear a yukata at least.”
- Literal: “As expected, you have to wear at least a yukata.”
- “Since you're going to the festival and all...”
Key Points
1着( なくちゃ = have to wear
- The verb is 着
( る “to wear”; its negative stem 着( ない becomes 着( なくちゃ in this obligation pattern. - 〜なくちゃ is a casual contraction of 〜なければならない or 〜なければいけない, used here as “have to”.
2せっかく…んだから sets up the reason
- せっかくお祭
( りに行( くんだから means “since you’re going to the festival after all”. - The んだから gives the reason for the mother’s suggestion.
3やっぱり adds “of course”
- やっぱり frames the yukata as the expected choice for a festival, matching the translation’s “really”.
4浴衣( くらい softens the expectation
- くらい presents the yukata as the least fitting thing for the occasion: “at least a yukata” or “something like a yukata”.
5Final ね makes it conversational
- The sentence-ending ね invites agreement, so the line sounds like friendly parental guidance rather than a strict order.
