How to sort a column by size

Hello,

Hi, I get an excel file every week with varying amount of records and i have to rearrange it so all the records are sorted into tshirt size then color:

eg.

Rec Name Size Color
1 John S Blue
2 Jill L Red
3 Jack M Green
4 Jono XL Blue
5 Jan X Red
6 Juan S Green

I need the data to be sorted so the sizes go from s,m,l,xl,xxl then the colours..

How would I write a macro in excel for this?

thankyou!
