Ridiculous & Fun
It's hard to write anything about this costume without laughing. On my tall 4 year old it's too big. Luckily it is for 4-5 yr olds, so I'm sure by Halloween he'll grow into it. Everything is included except pants. Seems pretty good quality as a higher priced costume. I'd definitely snatch it up on a sale though. Have to be careful with the plastic cane that screws together from 3 pieces. It is thicker, but very easily bendable.
This costume is of Halloween quality
At this price point, this costume is beyond acceptable the accessories are thin cheap plastic and the stitching quality is modest at best, but where this outfit shines is it looks exactly like the photo, and for a single use or limited use it is beyond acceptable so I gave it 5 stars. I would say expect Halloween costume quality, but honestly at this price point it is what I fully expected.
Easy Dress‑Up Set
The beret hat, bow tie, suspenders, glasses, and cane all fit comfortably and are lightweight enough for toddlers and young kids to wear without fussing. The pieces feel durable for playtime and photo sessions, and everything looks just like the pictures—cute, silly, and perfect for school events, 100‑day‑of‑school celebrations, or costume parties.
