If the walls are purple instead of gray, look at these:

painting would give you quicker results. Change the light fixture to a dramatic chandelier.

The clothes will be all the pizzazz you think wallpaper will add.

A metallic gold ceiling would be fun with any color walls.

Thank you Lyn. if I paint what color would you suggest for the chalkwall? Ceiling being as it is.

Thanks Apple_pie_order.

I am not looking to repaint all the walls. May be a wall along with the chalkwall to balance the colors.

I see you have a colourful collection of clothing so I would keep the decor neutral. You seem to have a few nicks on the walls and quite a few stickers which will most likely leave marks when removed. Why not take this opportunity to start fresh? Painting isn't difficult and really not expensive. Then if you still want wallpaper, I'm suggesting a neutral mural (see details below). Then install curtains on the window, replace the flush ceiling light with a long white tracklight for good lighting in the room, place a wicker chairs and side table in the room for your clients.

Paint the walls and ceiling a warm white in a matte finish and the baseboards and trim in the same white but a satin finish.

Here's the info on the mural:

Thank you lisedv.

I like the idea a lot. And in my personal taste I would want soft neutral tone. Just that i find painting little more messy. Therefore, thinking of going the mural/wallpaper way.

I will still explore the idea. Thank you.

on second thought, Prerna Bagla, I would leave the chalk wall as is (clean if off)

You, or someone with great lettering skills could write the name of your boutique and add other useful information, like 'all sales final' store hours, closed Sunday's & Wednesday's 'Cash Only, you get the piecture. It's part of the fun of the room.

If you are hell bent on painting it a color, how about choosing a Business Color, use that color for tissue paper, or any other promotional material. Looks like an interesting project, Have Fun!

That does sound fun Lyn!

Thanks again

BeverlyFLADeziner thanks a lot for your suggestions.

The clothing is what you want to show not some busy wallpaper and a nice big mirror much needed IMO and I agree the shelving system will m ake this look much more professional looking
