I like the first one better, but I see what you mean about the colors in the second one. Mi have observed that florals are making a comeback. Which makes me happy!

Maybe get a color that occurs in both so you can switch them when the mood strikes. A grey pink would be stunning.

I like the 2nd one better. the darker palette seems more in keeping with today's floral trend, whereas the first pic looks like something my grandma would have chosen in the 80s.

the scalloped edge doesn't bother me. I think it's because the other items in that room are not very girly. the simplicity of the sisal rug offers a counterbalance. also note how uncluttered the room is in general.

as for the wall color, I feel like we need more info. can you post pics of your guest room? I'm curious to know what color the flooring is, and what you're thinking for other accessories.

Here is the floor colour. I won’t post the room because it’s a disaster right now. Haha I have ripped off all the 80’s paint coated trim, and I think the previous owners just let their kid run wild with what they nailed to the walls. So it just looks like blue walls with a ton of patches right now!

I haven’t decided on accessories yet.

I love the second one and think the scalloped edge is charming. I don't like the first one nearly as much.

colors that could work: #1 I'd choose a pale warm grey to balance out the girliness, and a simple rug like the one in the product photo.

or if you wanted more color, a sage green, pale robin's egg, or maybe even subtle pink. keep the color saturation low so it doesn't become too cutesy (esp the pink, that one will be tricky).

if in doubt, you'll never go wrong with a soft white. don't let it go too yellow.

I like #2 and would paint the walls a pale sage green. Then I would do lots of white, but not frilly, accessories like blinds or curtains.
