in 買っては, I need some explanation for っては part


Here is the reply I got after saying that I was interested in buying new
shoes.

> 靴買うならTシャツやいま使うもの買っては？！

I think I got the overall meaning however I’m a bit confused with “買っては”. I
don’t really get the “っては” part. Could you explain? Thanks for your help!




The ては is short for 「～てはどう(ですか)？」, "How about doing ~~?", "Why don't you ~~?

> ～を買っ **ては** ？ = ～を買っ **ては** どう(ですか)？  
>  ≒ ～を買っ **たら** ？ = ～を買っ **たら** どう(ですか)？

The ては in ～～てはどうですか **literally means "If~~"** (≒～たら).  
(ては = the conjunctive particle て + the binding particle は).  
So ～てはどうですか literally means "How is it, if you do~~?" --> "How about doing~~?"

"If you're going to buy shoes, how about buying / why don't you buy a t-shirt
/ t-shirts or an item / items that you'll use now **instead** (rather than
shoes)?"
