Wedding guest dress where to shop?

[FriendshipBraclet]

Got a wedding to attend in April and I want a dress with sleeves as I think it has potential to be chilly.
Bought a dress from ASOS and little mistress both midi length with sleeves and sent both back.
Want to go actual shopping but not really got a clue which stores to try. I don't want to spend anymore than £100 but for perfect dress I would go a touch higher. Any ideas where I should be looking?

Have a look at Monsoon

Oasis do a lot of dresses with sleeves,though they all tend to be a certain length and style, which doesn’t suit everyone.
I think the phase eight also do a lot.

Have you tried Reiss? Usually a bit over your budget (dresses start from £150) but they have a very good outlet, either online or in store if you’re anywhere near biscester village or gunwharf quays.

Coast have a good selection of dresses in their sale.
Phase eight also a good option.

Go to John Lewis or House of Fraser with a personal shopper appointment. Lots of concessions in store, and someone else will pick clothes to your requirements while you sit in a nice room. Take a friend.

Coast and Monsoon are my go to shops for nice dresses. Both shops have really decent sales too.

Coast , monsoon , oasis , warehouse ... wait a bit though as the spring stuff will come through a bit later .

As above go to a department store as they will have all the concessions in one place save traipsing around .

Also if you have a next account they have loads of 'brands ' so you can order them to your door for free and try lots on without messing about with money .

Have a look at Phase Eight dresses in John Lewis, or try Coast and Monsoon.

Sorry, forgot to come back after super busy day
Thanks for all the suggestions I've booked a train to Edinburgh so will have a good time looking in all.
I think I'm in that age bracket (38) of not wanting to look too young but not too frumpy.

I always buy occasion dresses on eBay. A lot of people buy a nice dress, only wear it once and sell it once it’s sat in the wardrobe for a year.

Got a beautiful Coast dress for £12 last year. It was immaculate.

French Connection do some lovely dresses too.

Depending on type of wedding and what you do week to week, you could consider getting something that would double for work, like a really nice shift dress in a flattering colour and quality fabric? I have found it a solution to feeling grown up but not frumpy.

I'm saying Coast too. I've got a few dresses for weddings from there. Have you any ideas in mind OP? Style, colour etc? What size/height are you?

I'm size 12, big boobs smaller waist with big hips and thighs and 5"4
This is what I ordered from ASOS and sent back as it just didn't feel right.
