## Questions & Answers

**Q: Hi, my son is 5 he’s a tall boy, also a little bit big. I was wondering would 5-7 be bigger enough is it roomy as don’t want it to be tight**
A: These are the dimensions of the child for each of the sizes, if he is close to any shown then I would advise going one size larger to allow for clothing and room for some growth.

Age	Height	Chest	Waist
3-5 years	110cms	56cms	52cms
5-7 years	122cms	60cms	54cms
7-9 years	134cms	65cms	57cms

**Q: my daugther is 5 but tall for her age i need to normally buy her 7 year old clothes am i better buying the 5to 7 year ols or 7 to 9 year old one**
A: It's best to measure her and go for the one that allows a little growth room, sizes are:

Age	Height	Chest	Waist
3-5 years	110cms	56cms	52cms
5-7 years	122cms	60cms	54cms
7-9 years	134cms	65cms	57cms

**Q: What are the dimensions of the packet or box it comes in?**
A: I'm really sorry I can't remember. I ordered three different costumes and other items too and it was six months ago. 
Each one was in a packet possibly 45cm x 30cm but can't remember the depth (too deep to go through a letter box). They are fantastic costumes though.

**Q: Hi my son is 3-4 but he’s really short so will a 2-3 year old fit him ?**
A: I bought my son Age 5-6 for his 4th birthday which fits fine.  He is average size.
