I need to purchase a good suit for a wedding and no standard suits from Zara etc fit correct. Can anyone recommend a good suit tailor or suit shop.

You could try Carlos in Lagoa opposite Santander bank, they also make alterations if necessary.

The suit shop (Fato) under the food hall at Portimao retail park, some amazing prices at the moment.

There is a very good one in the Algarve shopping centre, can't remember the name of it but it is at the food hall end on the corner, they have some lovely suits, jackets, trousers and shirts and not too bad a price either, especially if they have a sale on.

Try the gent's clothes shops in Portimao "high street".

I think the shop at Algarve Shopping is called Arrow it is on the top level on the corner
just before the food entrance, very good quality and as already said good value at Sale
time.

Massimo Dutti has a branch at Algarve Shopping on upper level that does usual suits etc

I would also recommend Arrow. I recently bought a lovely tie in the sales, good selection too.
